Abstract
Abstract A rectangular neoprene foam gasket for application to the inside of a journal box lid has generally U-shaped aluminum frame members embedded therein with the arms spaced apart and intermediate sections along the sides having channel shaped extensions for overlying the respective inturned edge portions of the lid. The arms of the frame members are of different lengths with the shorter arms spaced from the longer arms. The gasket comprises two pairs of generally L-shaped oppositely disposed sections overlying each other and adhesively secured to opposite sides of the frame members. Tabs extend from the outer flange of each channel section and they have lengthwise extending ribs to facilitate retention in bent over position on the outer surface of the lid.
