It also offers all advantages of the GBMU4D range: vandal-proof, adjustment of height, depth and distance between gate and post, left/right interchangeable so it can be used for both left and right turning gates. BOLTON4D is available in M12 and M16, and always in 2 versions: one with Quick-Fix on both sides and one with Quick-Fix on the post, and on gate side a bolt through fixing for gate frames from 40 to 60 mm.
