TL and TS brackets are the preferred method of fixing. They give a tight, secure fixing. A powder coated pozidrive machine screw in the top of each side panel secures and releases the cover.

SB fixings are employed primarily on open ended side panels but also on standard end panels when the top fixing screws are not accessible. Covers over 2400mm long are made in two sections and use side fixing battens both on the side panels and for the centre fixing to join the two sections together.
