Coupler Fittings

Pressed Double Coupler
Pressed Double Coupler are used to connect two scaffolds at right angles. These critical components reinforce scaffold structure and can bear heavy load to disallow slip & distortion of the structure. The design is supported by a strong one piece body with T-bolts and flaps that can be easily removed for replacement or maintenance.

Pressed Swivel Coupler
Pressed Swivel Couplers join two scaffold tubes at any angle to provide a ledger brace, faced or similar bracing.

Sleeve Couplers are used to connect two scaffold tubes at both the external ends. A steel divider positioned centrally enables equal infixing of each tube. They can be introduced where the tension joints are required and therefore are particularly used with ledger tubes and long bracing.

The coupler connects putlog or transom tubes with the ledger tubes to the support of scaffold boards. The molded one piece body has been press-formed and designed to render the maximum resistance to movement. The Putlog Coupler has a long working life.

The Girder Coupler is used to connect scaffold tubes to girders and other steel sections which demand a specialized fitting with a high degree of performance. The Gravlock Girder Coupler has been especially designed to fasten either horizontal or vertical flanges, and can accommodate up to 43mm (1 ¾'').

Gravlock Coupler can be effectively used for erection; it allows the fitting to be bolted to the girder first, and leave both hands free to present and lock the tube. The fittings are made only for the compression joints, and it should not be used where tension can develop in the tubes.

Provides end to end connection of scaffold tubes. Operates by being inserted internally and expands to apply grip against the inner walls of the tubes. The fittings are designed only for compression joints, and should not be used where tension can be developed in the tubes.

The Putog head adopter is used to modify a scaffold tube into a putlog, ensuring the maximum use of short lengths of tube.

The stair case coupler is used for the construction of make-shift stairways by connecting together scaffold tubes and timbers (often scaffold boards) in angles varying from 28° to 90°. These units can be used in either left of right hand combination.
