CRL Wedgits are steel springs available in three widths. They are used for filling up the space and preventing rattles when using glass or plastic that is thinner than the channel it is being used in, or to center glass panels in wood or metal channels prior to sealant application. By placing Wedgits directly opposite each other at regular intervals, the glass will maintain a uniformly spaced position in the center of the channel, promoting a more even distribution of sealant on both sides.
