The new and improved Single Shot® Insulating Suspension Clamp now offers the Plumbing Professional more easy-to-install options First, a new key-hole closure assists in the pre-hanging of pipe - the installer can pre-set the Single Shot® to the joist, slide the pipe into the clamp, and then set the nail. Alternatively, the installer may slide the pipe into the Single Shot® , then simply nail it into the joist. Second, a new stabilizing foot allows the clamp to rest against the joist to eliminate rocking or movement of the clamp and pipe. As always, the Single Shot® can be used anywhere the standard insulating suspension clamp is used, through a stud or hanging below a ceiling or basement floor joist. With the preloaded nail, installation time is cut in half and no more fumbling for a nail while holding up the clamp.
