M4 Ultra Comfort Waist Straps

This is a kit to install the new M4 waist straps on existing units. These waist straps require some installation. The instructions can be found below. 

1. Install the new M4 door with the lumbar padding. Use the outside padding border to position the hinge onto the base.
2. Holding the hinge in position, drill 3/16" holes through the top and bottom hinge holes for both sides. 
3. Insert 2 bolts into the top and bottom holes and tighten with the locknuts provided. Do this for both sides.
4. Line up the hinges and insert the spring pins, making sure that the bottom edge locks into place.
