Spex Amphibian Eyewear Replacement Straps come with the necessary mounting hardware. Replacement instructions can be found in the images. When replacing your old strap, the medical rivet WILL NOT come apart. You have to cut it off of the old strap or stretch the neoprene over the medical rivet like the button on an pair of 501 Levis. Call us if you have any problems. 949.548.5100
Once the Medical Rivet is together, it can not be taken apart. It is permanent. Your new strap will have all the necessary hardware for easy installation. Feel free to give us a call too. We are happy to help!
