If ordering 4 or more keyed alike locks you can have them set up as different groups. If Required: Let us know the details in the "Specific Key Requirements" field above.

Each group of locks will then receive keys.

A backup restraint. With defined limits.

A gate restrainer helps prevent a gate falling to one side if its hinge fails. It is a backup device, rather than a replacement hinge. Fit it near the top hinge and leave it free to move throughout the gate’s travel.

The guide specifies 13mm mounting holes, 30–50mm above or below the top hinge. For box section 40mm or less, mount the restrainer on the side the gate swings towards: inside for an inward-opening gate, outside for an outward-opening gate.

Match the cable. Check the installation.

  • GRS03: 3mm cable and 220mm operational length; manufacturer testing covers gates up to 260kg under its stated conditions.
  • GRS04: 4mm cable and 275mm operational length; tested up to 500kg under its stated conditions.

The stated limits depend on gate width and installation. The product page recommends a maximum 2500mm gate width; consult the exact model’s report and loading chart.

The restrainer is not designed to carry the full suspended gate weight. If it becomes taut before the bottom of a failed gate rests on the ground, the manufacturer’s cited test does not apply. Do not repeatedly bend or crease the cable; inspect it at least every six months.

Installation and test evidence.

Read the fitting guide and the report matching the selected cable. These explain the mounting conditions and the tested setup; they do not certify every gate installation.

FAQs

No. It is a backup restraint intended to help prevent the gate falling to one side following hinge failure. It is not designed to suspend the full gate weight.

No. Width, mounting positions, cable travel and ground clearance also matter. The published test does not apply where the cable becomes taut before the bottom of the gate can rest on the ground. Read the exact model’s report.

The manufacturer recommends inspection at least every six months. The cable should move freely and must not be subjected to repeated bending or creasing.

Yes. The restrainer is supplied with plastic cover bushes for the mounting holes. These protect the gate finish and allow the cable to move freely.
