Pro-safe 4x5SF11 Fixed Shade Welding Lens Shade 11

Product Description

The PRO-SAFE 4x5SF11 is a fixed shade welding lens rated at Shade 11, designed for use in welding helmets and goggles that require a passive, non-auto-darkening filter plate. Measuring 5.25 inches wide by 4.5 inches high, this lens filters intense arc light and radiant energy during MIG, TIG, and stick welding operations. At 0.264 pounds, the lens is lightweight and sized for standard welding headgear filter frames. It meets ANSI Z87.1 requirements for optical and impact performance, making it a code-compliant replacement for fixed-shade filter applications in industrial and trade settings.

This lens is suited for professional welders, fabricators, and maintenance technicians working in industrial plants, construction sites, and fabrication shops. A fixed shade lens is the standard choice in applications where arc characteristics are consistent and the operator does not require variable shade adjustment. Shade 11 is typically specified for medium- to high-amperage arc welding processes. The 5.25-inch by 4.5-inch format fits welding helmet filter frames designed to accept this standard passive lens size.

Key Features

• Fixed Shade 11 filter for consistent arc light protection during medium- to high-amperage welding
• Dimensions of 5.25 inches wide by 4.5 inches high suit standard passive lens filter frames
• Meets ANSI Z87.1 for optical quality and impact resistance
• Lightweight construction at 0.264 pounds minimizes added helmet weight
• Passive fixed-shade design requires no batteries or electronic components

Compatibility

Designed as an OEM-style replacement fixed shade welding lens for helmets and goggle frames accepting a 5.25-inch by 4.5-inch passive filter plate with a Shade 11 rating.

Installation Notes

Installation of replacement welding lenses is typically performed by the welder or a safety equipment technician without specialized tools. The lens slides or snaps into the filter frame of the welding helmet according to the helmet manufacturer's instructions. Inspect the lens for cracks or scratches before each use, as a damaged lens must be replaced immediately. Lens replacement and eye protection standards in industrial environments are governed by ANSI Z87.1 and applicable OSHA 29 CFR 1910.133 requirements.
