CHAPTER 3: FOOTRESTS
Titanium Footrest
(ZRA)
Adjusting the Height
Tools Needed:
• 5/32” Allen Wrench
• Rubber Mallet
• Ruler
1. Loosen, but do not remove, the Allen screws in the two clamps that secure the footrest to the frame. See Figure
3-2. Loosen each Allen screw until the entire head of the screw is completely visible outside the clamp.
2. Tap the head of each screw with a plastic mallet to release the wedge inside the frame tube. This will allow the
footrest to move freely.
3. Place the end of a ruler on the floor and hold it vertically against the left corner of the footrest. See Figure 3-3.
Adjust the left side of the footrest to the desired height (not less than 2” of ground clearance) and tighten the Allen
screw in the left clamp so the left side of the footrest cannot change.
Note:
When adjusting the height of the footrest, make sure that at least 1-3/4” of the extension tube remains up
inside the frame tube. See Figure 3-5.
4. Repeat the procedure from Step 3 above on the right side of the footrest.
5. When both sides are set at an equal distance from the floor, make sure all four wheels are in contact with the floor
and make sure that the Allen screw in each clamp is in the most rearward position. Fully tighten the two Allen
screws in the clamps that secure the footrest to the chair frame, making sure the clamp remains securely butted
up against the end of the frame tube.

Replacing
Tools Needed:
• 5/32” Allen Wrench
• Rubber Mallet
• Ruler
1. Loosen, but do not remove, the Allen screws in the two clamps that secure the footrest to the frame. See Figure
3-2. Loosen each Allen screw until the entire head of the screw is completely visible outside the clamp.
2. Tap the head of the screw with a rubber mallet to release the wedge inside the frame tube. This will allow the
footrest (along with the clamp, wedge, washer and Allen screw) to be completely removed.
3. Insert the new footrest into one clamp and, holding the wedge in place against the clamp, partially screw the Allen
screw through the washer and into the clamp and the wedge. Repeat this procedure with the other clamp and
wedge.
