The single full height gate is fully adjustable – width can be cut to fit the opening size. The gate is supplied with reversible hinges, so it can be installed on the left or right-hand side of an opening.


Our industrial full height safety gates have been extensively tested to ensure they comply with safety standards BS 4211:2008 and EN14122-3:2016.

The gates have also passed a series of performance tests such as Salt Spray tested for corrosion resistance (672 hours) to guarantee continuous operation, even in corrosive environments and Life Cycle Testing which proved the range’s durability by withstanding 50,000 open and close cycles through 90 degrees. All test reports are available upon request.
