Panel Blocks and Multiblocks
Panel securing blocks allow you to fit panels to frames quickly and easily. The panels can be easily removed if required, because they are pre drilled with clearance holes for the screws needed to secure to the blocks. The different series have different blocks. The blocks are easy to fit and also reposition. Depending on the series, the panel block or multiblock permits different offsets to be achieved either by the use of spacers singly or in combination, or by rotating the block itself. All blocks have a securing nut which is semi-captive. The 2 types of blocks do basically the same job. Details of the differences between the 2 designs are illustrated below.

Panel Blocks
Panel blocks have a fixed distance from the front face of the block to the front edge of the profile. To change this distance, optional spacer plates are used.

Multiblocks
Multiblocks differ from panel blocks in that by rotating the base part of the block and also the top half, 4 different gap options can be created.
