Ridgeback Speed Bump Kit, 50mm or 75mm - Complete Kit with Free Delivery

Each centre section of the Ridgeback speed bumps features eight high visibility triangles that are bonded into the surface of the speed ramp. The sections are also retro-reflective ensuring they can be easily seen whatever the weather. The end caps feature a single yellow reflective triangle.

The Ridgeback is hard wearing and can be installed almost anywhere (where you have permission). The material they are made from conforms to BS EN 1436:2018 and BS EN 1824:201.

Different Speed Bump Options

• 50mm - Recommended for slowing cars down to around 10mph.
• 75mm - Suitable for slowing vehicles down to 5mph. WARNING: 75mm ramps can be harsh on cars, especially lowered and sports cars.

Every kit includes

• All speed bumps segments, inner and shoulders, to make up the length chosen.
• All fixings required - Our premium universal fixings are suitable for tarmac or concrete.
• All speed bump connectors
• 16mm, quality SDS+ drill bit(s) to install the kit.

Optional Extras

• 10mm pilot drill bit - this can be used to mark the ground with the speed bumps in place first
