VERSATILE DESIGN FOR VARIED INSTALLATIONS

There are two main body styles: Standard and Tubular, and two main catch forms: Standard and Chain, the main differences and the advantages of each model are detailed below.

All locks, except the Dual, can be used with as many padlocks, or as few, as the user requires by using the pin blanking kits supplied with every unit. This process is simple, secure and reversible.

STANDARD BODY AND CATCH ON AN RHS FRAMED GATE

For RHS or box section frames Multi-Latch can be easily installed using M10 10mm (3/8") dome-head cup-square bolts (coach or carriage bolts). A standard fitting template is supplied to ensure all the correct tolerances are observed during installation. We recommend that shear nuts rather than conventional nuts are used, however if conventional nuts are to be used the nuts should be welded in the tightened positions and the weld treated with zinc rich paint.

STANDARD MULTI-LATCH WITH BOLT-ON CATCH, MODELS 05-BC & 10-BC. FOR DOORS, GATES, CABINETS AND BARRIERS

05-BC STANDARD CATCH MULTI-LATCH

The diagram details the main dimensions of the standard 5 padlock unit. For ten padlock Multi-Latch (for model 10-BC add 150mm (5 7/8") to the overall body length, all other dimensions remain the same. The catch is 12mm (1/2") thick for both models.

These dimensions cannot be scaled up to 20 padlock Multi-Latch which due to expansion tolerances requires a larger catch.

Fitting instructions and blanking kit included.

STANDARD MULTI-LATCH WITH CHAIN CATCH, MODELS 05-CC & 10-CC. FOR GATES AND BARRIERS

05-CC STANDARD CHAIN CATCH MULTI-LATCH

The diagram details the main dimensions of the standard 5 padlock unit with chain catch. For ten padlock Multi-Latch (for model 10-CC add 150mm (5 7/8") to the overall body length, all other dimensions remain the same. The catch is 12mm (1/2") thick for both models and the chain has 8mm thick links in high tensile stainless steel.

Fitting instructions and blanking kit included.

TUBULAR MULTI-LATCH WITH CHAIN CATCH, MODELS 05-TK & 10-TK. FOR GATES, BARRIERS AND VALVES

05-TK TUBULAR MULTI-LATCH

The diagram details the main dimensions of the tubular 5 padlock unit. For ten padlock Multi-Latch (for model 10-TK add 150 mm to the overall body length, all other dimensions remain the same. The catch is 12mm (1/2") thick for both models.

All the critical dimensions for confirming compatibility between the Multi-Latch and any given installation are detailed below.

The Dual is not shown as it is a mobile device, however for reference it has a 10 mm (3/8″) thick shackle. The standard Dual is 140 mm long and has 45 mm internal clearance on the shackle. These units have 13.5 mm padlock apertures, although over bored models can be supplied with 14 mm apertures.

STANDARD MULTI-LATCH WITH STANDARD CATCH 05-BC

The diagram to the right details the main dimensions of the standard 5 padlock unit. For ten padlock Multi-Latch please add 150 mm to the overall body length, all other dimensions remain the same. The catch is 12mm thick.

Please note these dimensions cannot be scaled up to 20 padlock Multi-Latch which due to expansion tolerances requires a larger catch.

STANDARD MULTI-LATCH WITH CHAIN CATCH 05-CC

The diagram to the right details the main dimensions of the standard 5 padlock unit with a chain catch. For ten padlock Multi-Latch please add 150 mm to the overall body length, all other dimensions remain the same. The chain is 8mm thick.

Please note these dimensions cannot be scaled up to 20 padlock Multi-Latch which due to expansion tolerances requires a larger catch.

TUBULAR MULTI-LATCH WITH CHAIN CATCH 05-TK

The diagram to the right details the main dimensions of the standard 5 padlock unit with a chain catch. For ten padlock Multi-Latch please add 150 mm to the overall body length, all other dimensions remain the same. The chain is 8mm thick.

Please note these dimensions cannot be scaled up to 20 padlock Multi-Latch which due to expansion tolerances requires a larger catch.

CHAIN BARRIERS

Chain barriers such as those used in car parks and forestry access roads can also be adapted to Multiple access by installing a chain or tubular Multi-Latch (dependent on the post style) to the post and joining the existing chain to the newly installed Multi-Latches chain catch using a U-shackle (the shackle must be welded shut) it is also a good idea to trim the existing chain to length.

RISING OR COUNTER-WEIGHTED BARRIERS

Installation of Multi-Latches on rising barriers is dependent on the barrier design but the basic objective is to restrict the barrier from lifting when in the locked position. The ideal solution is to trim the post down and install the Multi-Latch horizontally on the top of the post so that the body runs parallel with the beam. The catch can now be installed onto the underside of the beam so that it enters the front catch hole from above, a rubber block fitted around the base of the catch block helps cushion the drop. However, many rising beams are quite flexible CHS (tubular or pipe) steel, designed to drop into a V shaped receiver. With this style of beam the above installation is likely to be unsuccessful and the use of a chain catch is preferred. Basically the Multi-Latch is installed horizontally or vertically onto the post below the v shaped receiver and a chain catch is used on the barrier beam to restrict the beams rise when in a locked position. If you have any questions on how best to install a Multi-Latch to a rising barrier please e-mail Technical Support or ring your nearest office and ask for Technical Sales (the provision of photographs of the barrier in question will help speed up the production of inquiry specific instructions).

SWINGING BARRIERS

The simplest style of barrier to fit a Multi-Latch to is the swinging type. To integrate the Multi-Latch first cut through the striking post just below the barrier beam. This should allow the barrier to swing over the top of the newly cut post. The Multi-Latch body is now mounted vertically onto the striking post with the rear catch hole protruding above the top of the post. The lower lip of the catch hole should be flush with top of the cut post and facing the beam in its closed position. If the post is circular hollow section (tube or pipe) then the longitudinal mounting slot in the back of the lock body should be used in conjunction with two dome head cup square bolts (coach or carriage bolts). Once the body is installed the beam should swing over the top of the post and slam flush with the protruding Multi-Latch. Next the catch is installed. Offer the catch up to the rear catch hole and fit all the padlock pins. Swing the barrier beam into its closed position and clamp the catch to the beam, now remove one padlock pin and swing the beam away from the post. The catch can now be bolted or welded into position. If installing onto steel posts the cut surface should now be made good with zinc based paint and the post should be filled with cement. If installing onto timber barriers shear nuts and large washers should be used during installation and the washers / shear nuts should be counter sunk into the timber to restrict removal.
