A common way of designing a large machine guard using aluminium profiles is to make the main frame members out of 80x40 section or larger, with hinged doors of 40x40 profile mounted flush. This gives a handy groove in the frame behind the doors, allowing the mounting of catches, door stops, safety switches, etc. Frequently, however, on grounds of either cost, space or even just what material is to hand, both the main frame and door frame are built from 40x40 section, making the mounting of ancillaries more awkward.
Demonstrating a keen awareness of what really happens (as opposed to what should happen!), Item is introducing a very neat Magnetic Door Stop. This comprises a folded steel plate that provides strength, even for quite large doors. This plate is neatly concealed behind a plastic moulding that bolts in the narrow gap between the door and frame, and incorporates a lead-in for the door. A steel striker is secured to a T-slot at the rear of the door, and is easily positioned to suit the magnet mounted in the rear of the stop. The magnet is cushioned so that even if the door is slammed shut, there is no damage.
The Magnetic Door Stop therefore performs the triple functions of door stop, cushion and catch. These products are available ex-stock from Machine Building Systems - see the 'new products' section of the MBS website for more information.
