RetractaBase

RetractaBase in the down position RetractaBase fully extended RetractaBase with polyethylene sleeve

SUMMARY

EB200 polyethylene sleeve over RetractaBase

A unique and patented solution for mounting temporary bollards, or where bollards need to be quickly and easily removed (or replaced).

Used with the Autopa EB100, EB200 or DDA100 (sleeve only, see Environmental Bollard page) the retractabase allows bollards to be removed, leaving no protrusion or trip hazard for pedestrians.

The base is pulled up by use of a size 1 manhole key.
When the bollard is removed the base automatically retracts in a spring controlled motion fully flush with the ground.
The bollard is fixed on by tightening a secure zinc plated steel clamp.

The EB bollards are hollow polyethylene and will not normally cause damage to a vehicle in collision with them. On impact the retractabase remains undamaged. If the bollard is damaged, it can be removed with the proper hand tools, and then replaced, thus avoiding costly foundation work, high labour charges, and blocking of the highway or pavement over a protracted period.

INSTALLATION

Determine the position of the installation
Break surface and make a hole approx 185mm deep by 500mm square.
Fill hole with approx 55mm of 10mm/12mm clean chippings to allow for drainage.
DO NOT USE CONCRETE at the bottom of the hole.
Lower the socket assembly onto chippings; The top disc of the socket assembly should
be flush with the ground or paving surface.
Add or remove chippings until desired height is obtained.
Fill remainder of hole with concrete mix and smooth off neatly to be flush with the top
surface of the top disc, leaving slight fall away.
Wipe any splashes of concrete from the top disc surface.
Leave for 24 hours before attaching the EB100 or EB200 bollard.
