New flush fittings from FDB

Rail transport is subject to especially high requirements in design, function and material. It creates a challenge for hardware manufacturers to combine the advantages of a flush-mounted quarter turn with those of a compression latch, while ensuring easy, tool-less adjustment of the cam

 

DIRAK offers a solution, now available from FDB Panel Fittings, which features a pair of flush-mounted compression latches made of stainless steel with different housing lengths, one with a fixed but exchangeable cam, the other with tool-less adjustment using a knurled wheel. All versions provide a precise compression combined with a flat surface. The two design styles – standard and toolless adjustable length - are of interest where a completely flush surface is important. They are discrete and safe since the flush-mounted design is adjustable to sit fully flush to the door surface. It thus avoids the risk of clothing getting caught, improving safety, and also looks more discrete. 

FDB says that the new flush fittings are especially suited to railway carriage interiors and similar where people require to move in confined spaces such as corridors with storage cupboards or access doors to side rooms without nuisance unlatching and door opening. The latches are also said to be well suited to external rail use where anti vibration, compression sealing and smooth surface are required. Likewise, for HVAC applications where anti-vibration and anti-corrosion performance supports appropriate IP ratings and for furniture construction where the discrete flush surface and firm gasket pull down enhance the operational look and feel of the equipment.

The whole latch is vibration-proof, as tested in accordance with DIN EN 61373, while offering a full 6 mm of compression and enabling safe contact pressure without any rubbing of the cam on the frame. For safety in operation the closing position is clearly visible with marks on the housing and insert for easy checking of the exact latching status.

The design incorporates two housing lengths of 28 mm or 37 mm which allow for different door thicknesses from 13mm to 22mm and for the versatile use of materials including wood, fiberglass synthetics and sandwich type boards. A wide range of H dimensions is possible: standard version H can be varied by exchanging the cam on the fixed version and on the adjustable version by use of the simple knurled wheel adjustment provided, plus there are different assembly options as the anti-rotation mounting flange can be used with countersunk screws and if using washers also with cylinder head screws or weld studs.
