Machine Building Systems is introducing the Quick Multiblock 8 for the Item aluminium profile machine construction kit, offering a rapid way of securing panels into frames, but allowing 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 quarter-turn, the pin is pulled slightly towards the multiblock and the panel is therefore 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 and avoid rattles. The hole in the panel needs 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 grey plastic in order to blend in with aluminium profiles, and they are available ex-stock from Machine Building Systems.
