Round Tubes - Upright Vertical
This page will walk you through how to mount to a wheelchair with round tubing, in the absence of any secure holes to mount to. For wheelchairs with holes available in the seat frame, refer to frame with holes
We try to avoid attaching to parts of the wheelchair that are designed to be removable:
IE: removeable footrests or armrests.
Throughout this page, we will deal with installing and mounting either the Bridge Clamp, Round Clamp, or the Collar Clamp.
It is important to measure the tube circumference so that you can order the correct size clamp!

HOW TO MEASURE TUBE CIRCUMFERENCE
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 may take up more room, but it is more secure wheelchair mounting. Clamping two tubes prevent each individual clamp from slipping. For heavier devices, if there are no holes or tracks to bolt to, we recommend implementing the bridge clamp.
In many cases clamping to a single tube is sufficient, or there may only be room for a single clamp. It may not be possible to clamp around the entire tube (as with the collar clamp).
With any "pinch-style" 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.

Collar clamps are very strong and come in a variety of sizes to fit most round tube wheelchair frames. They can be used in combination with a bridge or round clamp. They also can be used as a pair along an upright round tube and they are a good choice for mounting along a curved on a round tube.
