NIUQIUP Trailer Door Bumpers: Your Impact Protection Guardian Picture this: You’re hauling equipment in your enclosed trailer when a sudden stop sends the ramp door slamming against the truck bed. The metallic clang echoes through the cargo area as you cringe at the fresh dent. That’s where NIUQIUP’s 2.5" rubber bumpers step in – silent protectors standing guard between your trailer ramp doors, truck gates, and costly damage. Crafted from compression-molded rubber tested to withstand -40°F winters and desert heat, these 2.5-inch diameter bumpers act as shock-absorbing barriers. Each set includes 4 industrial-grade bumpers paired with M8x32mm screws and M8x30mm bolts, engineered to secure tightly on enclosed trailer ramp edges, RV door frames, or utility trailer corners. Why They Work Where Others Fail → Precision Fit: 0.3" pre-drilled centers align with standard trailer parts and truck accessory mounting points → Multi-Surface Defense: UV-stabilized rubber prevents scratches on both metal (dock bumpers) and fiberglass surfaces (boat trailer doors) → Silent Operation: 60% noise reduction compared to bare metal-on-metal contact during door closure Install them in minutes on cargo trailer bump stops, workshop machinery pads, or as vibration dampers under generators/air compressors. Backed by a 1-year manufacturer’s warranty against material defects, these bumpers are rigorously tested to endure 10,000+ compression cycles without cracking.
