Telescopic or retractable: what’s the difference?
None. Both names describe a post that drops down into a sleeve in the ground when you don’t need it. "Telescopic" describes how it slides into the sleeve; "retractable" just means it can be lowered.
How does a telescopic bollard lock?
Unlock it with the key, lift the post until it locks upright, and it stays there until you unlock it again. To lower it, unlock it and slide it back down into the sleeve so it sits flush with your drive.
How heavy is a telescopic bollard to lift?
It depends on the size. Bigger stainless posts can mean lifting well over 15kg each time. If that sounds like a chore, a lift-assist bollard has a gas strut that cuts the lift to around 6–7kg, and an automatic bollard does it all for you.
How deep does a telescopic bollard go?
The sleeve for a security bollard goes in around a metre deep, set in concrete, with drainage at the bottom so rainwater drains away instead of sitting in the sleeve, where it could freeze and jam the post. We check for cables and pipes before we dig.
Telescopic or automatic?
A telescopic bollard is the best value and gives excellent protection, but you lift it by hand. If you use the drive several times a day, or you’d rather stay in the car, automatic is easier to live with.
