support > Wheelchair Mounting > Round Tubing

The preferred way to attach to any frame is if you can utilize any existing bolt holes, this is typically more robust than clamping to a tube.
If this is not an option, you will need to clamp to the wheelchair tube.


If it is possible to clamp two positions not along the same tube, "bridging" the two tubes will provide really solid mounting.
This is why we have the Bridge clamp!
Bridge clamps often take more room, but it is a a more secure way to mount to a wheelchair.
Clamping two tubes prevent each individual clamp from slipping.
For heavier devices, if there are no holes to bolt to, we recommend implementing the bridge clamp.

Bridge Clamp attachment


In many cases or if there is no room, clamping to a single tube is sufficient.
With a single clamp on a round tube, there is an opportunity for the clamp to slip around that tube.
If possible, position the clamp to minimize danger if it were to slip.
ie: clamp to a vertical tube section, so if it slips - the device remains safe

About the Wheelchair Bridge Clamp(s) : 1" (WC-R1B) and 7/8"(WC-R7/8B)

The bridge clamps are smaller than the full sized round clamps, and must be used in a pair.
Bridge clamps are used to clamp to multiple tubes, eliminating the possibility of clamp-slip. We recommend this method for heavier devices.
A WC-AP2 is used to span the two bridge clamps - and the Wheelchair Brackets or extensions bolt directly to it.

To implement bridge clamps, you will need at least two bridge clamps and a plate to span them (WC-AP2).
Each individual bridge clamp should be appropriately sized to the tube that it clamps to.
(Tubing that is 7/8" in diameter should use the 7/8" bridge clamp.)
The strongest mounts will be if you can get both clamps perpendicular (90°) to each other.

Attaching the Bridge Clamp to Round Tubing

Tools needed:
  • 3/16" Hex Key (provided with every Mount'n Mover)

Attachment Instructions

1: String together the bridge clamp

Hold up the adapter plate to the wheelchair frame, and map out appropriate holes/slots to attach the bridge-clamps.
You will want to position the WC-AP2 so that the threaded holes (in red) will be as far forward on the wheelchair as possible.
Try and align the WC-AP2 so that it is vertical or horizontal with the ground - this enables the use of the Solid Wheelchair bracket

Loosely attach the WC-AP2 to the bridge-clamps together using the bolts and nuts.

Picture examples of this here and here. Attaching one of the clamps to within a slot usually gives you a lot more flexibility.
Bridge Clamp Pre-Assembly Illustration

2: Position the bridge clamps

Place both bridge clamps around different tubes of the wheelchair.
Incrementally tighten the bridge-clamps around the wheelchair tube so that you still can reposition each clamp to best suit your needs.
At this point, you will have several options to mount. You can insert and orient the clamps into many different holes or slots for flexibility in mounting. Keep in mind that you will want to keep at least two of the threaded holes clear so you can attach the next component. (Either the wheelchair brackets, or L-Angled extension)

The example below shows attachment to welded "T" tube:

Scenario A: Position 1

Because the "T" tubes have the same diameter, we will use two 1" Bridge Clamps.
This example shows the clamp bolts "below" both tubes.

Bridge Clamp Assembly A 1
Bridge Clamp A 1 Assembled

Scenario A: Position 2

With the same exact chair and side, we have to option to "flip" either clamp.
This position has both clamps flipped, moving the WC-AP2 higher, and further forward.
This may particularly be useful to get around manual wheelchair brakes, but may interfere with footrest swingaway/removal

The example below shows attachment to welded "J" tube:

Scenario B: Position 1

The "J" tube example has three different sections of tube welded together, with the curved tube smaller than the straight tubes.
In this example, we clamp to the both the straight tubes - using two 1" Bridge Clamps.

In this scenario, the WC-AP2 may not be parallel to the ground - so for an upright mount, we will have to use the Adjustable Wheelchair Bracket (WB)

Bridge Clamp Assembly A 1
Bridge Clamp A 1 Assembled

Scenario B: Position 2

With the same exact chair and side, we can instead clamp to part of the curved tube.
This requires using the 7/8" bridge clamp for the curved portion AND a 1" Bridge Clamp for the straight tube.
When clamped, the resultant WC-AP2 is parallel with the ground - great for using a Solid Wheelchair Bracket (WB2)

3: Attach the Wheelchair Bracket, or L-Angled Extension

Before you completely tighten up the clamps, hold the wheelchair bracket in place (solid or adjustable) to make sure the mount'n mover and post can clear arm rests, brakes, footrest and etc.
You may have to revisit step 2 several times, flipping the clamps or WC-AP2 to properly position the wheelchair bracket without interfering with other wheelchair functions.
Once the WC-AP2 is tightened down and secure, you can bolt either of the wheelchair brackets or L-Angle Extension directly to it.


Picture examples of wheelchairs mounted with the bridge clamps

"T" styled tube Position 1

inside view: bridge clamps attached to the T of the manual wheelchair   outside view: bridge clamps attached to the T of the manual wheelchair  
This shows two bridge clamps of the same size (both 1"), spanned by the WC-AP2. This position completely clears the swingaway for the footrest, but may interfere with an extended brake lever handle.

"T" styled tube Position 2

inside view: bridge clamps attached to the T of the manual wheelchair   outside view: bridge clamps attached to the T of the manual wheelchair  
This shows two bridge clamps of the same size (both 1"), spanned by the WC-AP2. The clamp on the vertical tube has been flipped from Position 1 to move the mount further forward on the wheelchair This position completely clears the extended brake lever handle, but attaching the wheelchair bracket may interfere with the footrest swingaway.

"T" styled tube Position 3

inside view: bridge clamps attached to the T of the manual wheelchair   outside view: bridge clamps attached to the T of the manual wheelchair   bridge clamp with adjustable wheelchair bracket attached   complete bridge clamp setup  
This shows two bridge clamps of the same size (both 1"), spanned by the WC-AP2. This position does not span as wide as the first two examples. Mounting components completely clear the extended brake lever handle and the footrest swingaway, but due to size constraints - we were not able to align the WC-AP2 horizontally. The resulting angle of the WC-AP2 requires the use of the adjustable wheelchair bracket instead of the simpler solid one.

Attachment for the bridge clamp on the "J" style of wheelchair. This is using two different sizes of bridgeclamp, the 1" on the main rail, and the 7/8" on the curved tube. The second picture shows the Solid Wheelchair Bracket attached. In this orientation, it may interfere with footrest swingaway/removal.

The solid wheelchair bracket is attached so that it is closer and higher than the position above.

About the Wheelchair Round Clamp(s) : 1" (WC-R1) and 7/8"(WC-R7/8)

The wheelchair round clamps are used to clamp to round tubing, where no mounting holes can be accessed.
You can attach Wheelchair Brackets directly to the Round Clamps, or you can use other accessories for more positioning options.

Tools needed:
  • 3/16" Hex Key (provided with every Mount'n Mover)
Attachment Instructions
  1. Align the attaching components with the holes of the Round Clamp.
  2. Insert the bolts provided thru both Round Clamp halves.
  3. Thread the locknuts provided onto the bolts, and tighten the bolts using a 3/16" hex key.
    Please note that you will not need a wrench, since the roundclamp already has a feature to hold the nuts in place.


Picture examples of wheelchairs mounted with the round clamp

Example 1: Round Clamp mounted to a Kids ROCK manual Wheelchair

side view: mounted Round Clamp using a WC-R1 and WB(adjustable)   side view: mounted Round Clamp using a WC-R1 and WB(adjustable)  

The mounting location shown here is part of the static chair frame, so adjustments to the chair should not change the mounting location.
A Round Clamp takes up 2" of space along a round tube, which was perfect for this specific wheelchair.

Components used: Wheelchair Round Clamp (WC-R1), and the Adjustable Wheelchair Bracket WB(adjustable)

Example 2: Round Clamp mounted to a Quickie Iris (Tilt-In-Space) Wheelchair & Footrest removal/attachment

side view: mounted Round Clamp using a WC-R1, WB(adjustable)   Close-up side view: mounted Round Clamp using a WC-R1, WB(adjustable)  

This tilt-in-space wheelchair allows perfect device positioning for the user regardless of tilt-angle.
During transport the footrests required removal, so we included a video showing footrest removal and attachment after mounting.
The client also had a slidetrack power-wheelchair mounted, so that he have full access to his device in either chair - without changing any settings.

Components used: Wheelchair Round Clamp (WC-R1), and the Adjustable Wheelchair Bracket WB(adjustable)

Example 3: Round Clamp mounted to a Quickie Zippie 2 Wheelchair

side view: mounted Round Clamp using a WC-R1, WB(adjustable)   front view: mounted Round Clamp using a WC-R1, WB(adjustable)   top view: mounted Round Clamp using a WC-R1, WB(adjustable)  

The Quickie Zippie 2 is a very compact pediatric chair, with very little space along the seat rails to mount.
Since footrest removal was not a concern for this client, the Mount'n Mover was mounted on the removable footrest upright.

Components used: Wheelchair Round Clamp (WC-R1), and the Adjustable Wheelchair Bracket WB(adjustable)

Example 4: Round Clamp mounted to a Invacare Ranger X Wheelchair

side view: mounted Round Clamp using a WC-R1, WB(adjustable)   front view: mounted Round Clamp using a WC-R1, WB(adjustable)  

The Invacare Ranger X power wheelchair shown is an older model with a round tubing seat frame.
We reccommend using our Adapter Plate 1 or 2 if there are mounting holes along a round tube. This is typically stronger and will not slip with serious use.
