This free-standing Protect-O-Screen® protects workers, material, and equipment from the hazards of welding sparks, spatter, and UV flash. Constructed with 1" crossbars and 1-1/8" corners and legs, the sturdy 18-gauge black steel, rust-resistant, enamel-finish, square tube frame is designed to eliminate the slipping and twisting that occur with round tube frames. The Quick-Snap™ connection allows quick and easy assembly without tools. The unique modular design allows addition, removal, replacement, and rearrangement of individual panels to quickly adapt to new requirements. The 24" platform legs can be turned 90° to prevent interference with adjoining screens. Optional casters are available separately.
