Location: western PA | Various extrusions are sold in lumber yards and big box stores, for the installation of house hold soffit and facia materials. These include "H", "F" and "C" shapes, some or all may be adapted to your needs. They are aluminum, so unless a barrier coating is added, they cannot be used on steel trailers. Some will not support a 1/4" inch material, but many will work with 3/16" sliders. Add a bit of lubricant to the bottom track to ease the window's movement. Adding drain holes to the bottom track will prevent the water from accumulating inside. |
