Type FP9 glazing packers can help make your installation unit more secure and stable. When used to level off installations or to pack glass, our glazing packers help prevent deflections of a unit from its frame. The Type FP9 glazing packer’s are also useful to spread the weight of an installation more evenly, and to support hinge points. These glazing packers are also great for making sure your installation is vertical and square to the frame it is in.
