The bollard (3) is able to slide inside a housing (1) between deployed and retracted positions. The housing contains a cover (4) with a central sleeve (12) which acts as a stop for the base of the bollard when it is deployed. The bollard incorporates at least one additional cover (10) with a sleeve (12) which fits on top of the first with its lower section engaged in the upper part of the first cover (13) and forming an extension to the first cover's sleeve. The first and second covers are linked by tubular spacers (9) with holes for long bolt fasteners. |
