1-800-BOLLARDS low-speed crash tested (ASTM F3016) (5000 lb. vehicle @ 30 mph) 8” diameter internal-locking removable bollards are the most versatile bollards on the market today. The locking mechanism engages below grade, inside the embedment sleeve. Internal-locking removable bollards are nearly impossible to remove without the Camlock key which is placed waist high on the bollard for easy access.
Internal-locking removable bollards are manufactured from carbon steel and are available in 200+ powder coat colors, or manufactured from Type 304 stainless steel or, for harsher environments, from Type 316 stainless steel, and the stainless steel is polished to a #4 finish for long-lasting durability.
