ABSTRACT:
An anti-rubbing block 9 for a friction stay, comprising a body 11 for positioning within a track 1 of a friction stay, the body 11 extending above the track 1 to prevent rubbing of a link 5 of the stay on the track 1, and a flange 13 extending from the body 11 substantially parallel to the track 1, during use, for attachment to a slider 3 of the stay such that the anti-rubbing block 9 moves with the slider 3 along the track 1 during opening and closing of the stay. Such an anti-rubbing block 9 assists in avoiding unnecessary wear and tear, especially when the slider 3 has a metal surface.
