The modular protective barriers are an affordable solution to warehouse and factory safety. The protective barriers are light weight allowing for easy lifting for maneuvering and installation. The modular barrier system features the "lift out" design making for a quick set up and assembly. There are many lengths of rails to choose from all the way up to 10' long! The rails can be cut to length in the field where custom sizes are needed! The 42" double guardrail meets OSHA guidelines for fall protection! The protective barriers are powder coated yellow for safety and visibility. The protective barriers are manufactured from a 11 gauge steel tubing and the columns have 8" x 8" 1/4" thick base plates. The modular barrier columns are capped off. Note: Fasteners NOT included.
