The JACKSON SAFETY 41594 is a polycarbonate inner safety plate designed to protect welding filter plates and auto-darkening filter lenses from surface damage during welding operations. Made from clear polycarbonate, the plate sits on the interior side of the welding helmet lens assembly, acting as a sacrificial barrier against spatter, slag, and abrasion that would otherwise degrade the primary filter. Lightweight at 0.05 pounds, this plate is a standard consumable item that welding technicians stock and replace regularly as part of routine helmet maintenance.
This inner safety plate is suited for use in both shop and field welding environments where lens protection is a priority. It is sold individually and applies to setups where preserving the integrity of auto-darkening filters is critical to maintaining consistent arc visibility and operator safety. The clear tint ensures no distortion of the filter lens view during use.
Confirmed compatible with NITRO Auto-Darkening Filters. Designed as an inner safety plate replacement for welding helmets that accept this lens format.
Installation is performed by qualified welding personnel or end users during helmet lens maintenance. Ensure the helmet is removed from service and all power to any auto-darkening filter battery or solar cell is isolated before disassembling the lens frame. Handle the polycarbonate plate by the edges to avoid contaminating the optical surface. Replace the plate whenever scratching, pitting, or discoloration begins to interfere with clear visibility through the lens stack.
