Bollard bayonet socket

This type of socket has a separate cover plate for use should the bollard be removed for any length of time. The cover plate should be stored independently from the bollard.
Should the bollard be removed frequently for any length of time, it may be prudent to purchase a second base unit, in order that the bollard can be securely stored.
Provision should be made by the use of a plastic tube (not supplied) through the concrete foundation to a drainage sump material below concrete level. This should provide adequate irrigation of rainwater.
