LCN 4011REGALLH Left Hand Size 1 Surface Mounted Pull Side Smoothee Heavy Duty Door Closer with TBSRT Thru Bolts 689 Aluminum Finish

The 4011 is a surface mounted door closer that installs on the pull side of the door frame. This heavy duty closer handles high-traffic commercial doors where reliable self-closing action is required for fire code compliance and security. The size 1 spring works for doors up to 32 inches wide in most applications.

LCN builds this closer with a forged steel main arm and double heat treated steel pinion for durability in demanding environments. The all weather fluid maintains consistent performance across temperature ranges. The cast iron body with aluminum finish provides corrosion resistance for interior and exterior applications.

The left hand configuration matches doors that swing away from you when the hinges are on your left. Peel and stick templates simplify installation. The TBSRT thru bolts provide secure mounting to hollow metal frames.
