Speed Bump Installation Guide
- An even surface with a minimum depth of 100mm.
- A hammer / SDS drill with a 1/2" / 13mm chuck.
1. Lay out the speed bumps in the desired location. Ensure that each speed bump lies flat on the surface and in a straight line. Use the black speed bump connectors (two connectors per section) Uneven fastening may place uneven stress on the speed bumps.
2. Mark the holes to be drilled, making pilot holes, with a smaller drill bit. Take care to mark these as accurately as possible.
3. Move the speed bump from its position, and drill the four holes using a 16mm masonry drill bit.
4. Hammer the nylon plug section of the fixing into the hole.
5. Place the speed bump back into position, aligning the fixing points of the speed bump to the plugs, then insert the coach screws.
6. Tighten the bolts so that the speed bump is firmly held in place. Remember to tighten evenly and tension the bolts in a diagonal manner.
