The Ergo 4373BK: Ergo Low Pro rail covers serve a dual purpose of protecting unoccupied rail areas from potential damage and shielding the operator from the sharp edges of the rail. This aids in preventing any damage to equipment like rappelling ropes which may otherwise be abraded or cut by exposed rail sections.Another significant attribute of these rail covers is their Santoprene construction. This provides a low-profile, rubber-like grip surface that notably enhances weapon control.
