Sharks Teeth Ramp - Mid Section The Sharks Teeth Ramp is a modular, directional flow-control plate for restricting vehicle movement to one direction. Five spring-loaded tooth cartridges lie flat as a vehicle passes over in the permitted direction and spring back upright to obstruct travel the other way. Built from heavy gauge steel, it is rated for cars and HGVs. This listing is for the mid section only - end caps are sold separately, and sections link together to build a ramp the full width of a road or access lane. Key features Suitable for cars and HGVs 5 spring-loaded tooth cartridges per plate, each individually replaceable without removing the ramp Heavy gauge chequer-plate steel, powder-coated black with yellow cartridges Built-in 10mph traffic calming action Surface-mounted - no drainage channel required Bolts straight onto tarmac or concrete, 4 bolts per plate Mid section - end caps sold separately Where it's used Car park and retail site entrances and exits Facilities management access routes Local authority highways and street works Sites where cars and HGVs share the same route How many plates do you need Plates are added side by side to cover the full width of the road or lane. As a guide: a 3m-wide road needs 5 plates, a 5m-wide road needs 8 plates, and a 7m-wide road needs 12 plates. Check with our team for the exact count for your site. Specification Dimensions Length 500mm Width 490mm Plate height 50mm Height including teeth 100mm Weight 20kg Details Configuration Mid section - end caps sold separately Tooth cartridges 5 per plate, individually replaceable Fixing Bolt down, 4 bolts per plate Drill hole size 24mm tarmac fixings Mechanism Built-in counterbalance and heavy-duty spring Plate material Heavy gauge steel, powder-coated Teeth material High density polyethylene Colour Black chequer plate with yellow cartridges Installation Plates bolt down onto tarmac surfaces older than 6 months with at least 50mm of asphalt depth, using rubber expanding fixings into 24mm drilled holes. On newer tarmac, or where the surface isn't suitable, a concrete raft should be laid first. Fit plates on a level, straight run, away from junctions and turning areas - avoid gravel surfaces and inclines, which put extra strain on the springs and fixings over time.
