Abstract: A snow guard for a raised portion on a building surface, having a unitary transparent mounting body is formed from a polycarbonate material. A transparent acrylic snow-holding bar fits into the transparent mounting body. An ice-holding bar also is provided and is formed from clear acrylic. In one aspect, the mounting body includes vertical structural stiffeners 30 by walls 42 of bar supporting central columns 32 and by outside surface 38 of wall 24 and horizontal stiffeners 27 extending downwardly under top 26 and which are integral part of the mounting body and of walls 24 providing a rigid, strong connection of the two structural support sides 28, top portion 26 and horizontal stiffeners 27 and structural support sides 28 all molded in one piece, made of ultraviolet proof, high impact, high izod polycarbonate plastic. In one aspect, the mounting body include bar insertion cavities 46 and stops 52 to prevent snow-holding bar 8 from sliding through its insertion cavities.

Abstract: Disclosed herein is an improved arrangement for the operation of an overhead garage door that comprises an adapter utilized for installation and periodic maintenance of the support arrangement. Also disclosed is an adapter for use with existing garage door structures, improved wrenches for use in tensioning coil springs usually found in such arrangements and a method for tensioning such coil springs when they are originally installed or during periodic maintenance of the springs. The adapter comprises a body that may be mounted upon a rotatable shaft that supports the coil springs and be non-rotatabley attached to an end of the coil spring and the rotatable shaft. The attachment to the shaft is a releasable connection and the body has splines or projecting abutment surfaces so that two of the improved wrenches according to the present invention may have their jaws closely surround and engage the splines on the body.
