What are different Lock Types?
Integral: these are locks built into the Post, they can be located at the top or bottom (depending on the model chosen), they are the more convenient type of lock but would be more problem in the event of vandalism or mechanical problem.
Padlock: these are padlocks fitted at the bottom or top (depending on the chosen model).
Both types of Locks can be purchased as K/D (keyed to differ) or KA (keyed alike), keyed alike are ideal for when you have multiple Posts or Bollards and a single Key will operate all.
Which Type Of Bollard Should I Choose?
Ground Clearance & Risk Assessment:
Is the location of the post going to have low chassis cars or motorcycles driving over them or perhaps tight access meaning that you have to drive over the location of the Post, or are they located where the general public or staff may be walking over them ?
A Fold Down Post or Bollard will lay on the ground when not in use, for the vast majority of applications this does not cause a problem because they are on private ground and the owners can ensure that there vehicles will be able to safely drive over the post they have chosen.
A Removable Post or Bollard comes supplied with a ground spigot and flush fitting hinged top lid, when it is removed it results in there being no ground obstruction at all, very safe, but you have to store the post somewhere (in a boot of a vehicle, in a nearby building or quite often in a second spigot fitted onto the side of the access).
Fully Telescopic Posts & Bollards leave no ground obstruction at all, together with not having to worry about storing it elsewhere as it has retracted into the spigot base underground. They are the strongest type of Post & Bollard around but take more time in fitting, you also have to ensure that there are no underground services in the location as you would be digging down into the ground 700 mm or more (depending on the model you choose).
The other choice would be the unique 620 Fold Away, this is a combination of a telescopic and fold down, the tray is buried horizontal under ground, the post folds away into this box when not in use, the box has a lid which leaves the ground totally flush.
