Qty:
  1. Sections ( E ) & ( D ) cannot be less than 5”.
  2. Maximize the width of section ( C ) still allowing the seat to drop into the cross rails without interference. For example, using a 16 wide wheelchair, the maximum width of section ( C ) cannot be wider than 9½”.  Any wider than 9½” the cross bars will not allow the drop hooks to be bolted flush to the seat rails.
  3. The seat cushion must be at least 2” or more thick to prevent the user from feeling the cross bars when they sit.  If the seat cushion has a semi rigid foam base, the base must be notched for the cross bars.
  4. When the seat fits between the seat rails the maximum width of the seat in section ( A ) is: wheelchair frame width, minus the left & right seat rail diameter, minus 1” this equals the total width of section ( A ).

Example:  wheelchair frame width:   16
Left seat rail diameter:                     - 7/8

Right seat rail diameter:                   - 7/8

Minus:                                                 - 1”

Section ( A ) width:                         13 ¼ ”

  1. Drop hooks are bolted to seat rail, into existing seat rail upholstery holes if possible. The drop hooks are attached to an extrusion that allows you to slide the hooks forward and back in section (D) and (E) in the schematic above.   If the hole in the drop hook doesn’t line up with the seat rail upholstery hole, the seat rail must be drilled to allow the drop hook to be bolted to the seat rail.  To move the drop hook, loosen the 5/16 nut holding the 90 degree angle to the extrusion, slide to the desired position, the drop hook hole lines up with the seat rail hole and then tighten in place so nothing moves.  If a hole needs to be drilled in the seat rail use a 3/16 drill bit.  Insert the screws provided through the drop hook, the seat rail and into the lock nut provided.  Tighten the lock nut in place.
