More about Self-assembly gate safety edges and parts

What parts do I need to build or repair a safety edge?

Start with the exact profile reference and the length required. Depending on the system, you may also need a matching aluminium carrier, end caps, cable connection and resistor or termination components. A length of rubber profile is not the same purchase as a finished, connected edge. Check the product's sale unit and contents before adding the other parts.

Can I replace one profile with another?

Keep the full code, including letters after the profile size. For example, an ASO SENTIR 25.45 TT should be identified as TT rather than shortened to “25.45”; a similar-looking ST profile is a different reference. Compare the manufacturer's drawing and the existing carrier, end treatment and connection before selecting a substitute.

How does the edge connect to the gate?

The edge must suit the gate's existing monitoring arrangement. Check the sensing circuit and the controller or transmitter it connects to; an “8k2” description alone does not identify the right wireless kit. Browse safety-edge controllers and wireless kits for the electronic side of the system.

Not sure what you have? Send us the full reference and photographs of the profile, carrier and cable end. We can help identify the matching components. A competent installer should assess and test the complete gate safety system; do not bypass a failed protective edge.
