Abstract:
Herein is disclosed a sleeve system and methods of using the system. The system uses an elongated open-ended sleeve, and mounting plate parts which mate with each other to form a mounting plate and which are securable to each other and to a wall. The mounting plate thus formed comprises a collar which, when the mounting plates parts are secured together, presses against portions of the outer surface of the sleeve to hold the sleeve in place.
