WRS Vent Arm Shim - 2-1/2"

Shims are used for making slight adjustments to home elements, such as door frames and windows, to make them level. Once a window is seated into the opening, place shims in any gaps between the window casing and the framed opening. Use a hammer or mallet to gently tap the shim into place, using a level to check that the window or door is as level as desired. Measures L: 2-1/2" x W: 3/4" Center Hole to Center Hole Dimensions: 1-7/8"
