QRM Receiver EPDM O-Ring, replacement (each)

Dive Rite's Quick Release Mount System (QRM) uses a system of rollers and bands to easily clip a light head into the mount. The system is made up of two rollers, one fixed and one moving, joined together by a pair of heavy duty EPDM o-rings, all on a receiver plate. (The receiver always includes a spare pair of EPDM o-rings.) When the striker on the light is pushed against the front, moving roller or the receiver plate, the EPDM rings allow the front roller to move forward. Placing the striker into the channel of the receiver plate, pressing forward against the front roller and releasing, the EPDM rings will retract, securely holding both sides of the striker under the rollers. To release the light head, simply push forward on the light head. The EPDM rings will stretch, the front roller moves forward, and lift up on the back of the light head. The strikers on the light head will be free from the rollers.
