Removable bollards

A removable bollard blocks a lane most of the time and lifts out when a truck, a fire engine or a snowplough needs through. The post drops into a sleeve set in concrete and locks in place.

What to check before you order

  • Weight. A 4½ in removable lifts out by hand; ännt’s 273 mm crash-rated removable post weighs 92 kg, which is a two-person or a lifting-aid job. Decide who will move it and how often.
  • Winter. A sleeve full of ice won’t take the post. Ask for a sleeve cap or a drained sleeve, and keep the key somewhere the plough driver can get it.
  • Rating. A removable can be crash-rated (ännt RM150, RM275; Gibraltar G-1631R), but only when its sleeve is installed to the tested foundation.
  • Fire routes. If the bollards cross a fire route, the fire department sets the rules for how they open. Ask the local fire prevention office.
