The new Quick Multiblock 8 for the Item aluminium profile machine construction kit offers a fast way of securing panels into frames, but allows almost instant access where desired.
The multiblock is inserted into a Line-8 frame with a push-and-twist action, and a clearance hole is drilled near the edge of the panel. However, instead of a sliding M6 nut inside the multiblock, there is a curved steel plate spring. This is so arranged that when a mating fixing pin is pushed through the hole in the panel, and into the Quick Multiblock, then given a 1/4 turn, the pin is pulled slightly towards the multiblock and the panel is thus clamped securely in place.
Altogether, three types of securing pins may be chosen: an inexpensive plastic one with a hand-grip; an identical but more durable zinc die-cast pin for frequent use; and a zinc pin with a neat coin-slot in the face. All pins incorporate an 'O'-ring to maintain pressure on the panel thus avoiding rattles. The hole drilling in the panel need only be approximate: like the standard screwed multiblocks, the design allows for a generous tolerance in the hole position.
The Quick Multiblocks are made from a grey plastic in order to blend in with aluminium profile, and are available ex-stock from Machine Building Systems of Ripley, Derbyshire.
