LCN 4013TSTDALLH Left Hand Size 3 Surface Mounted Pull Side Smoothee Heavy Duty Track Door Closer with TBSRT Thru Bolts 689 Aluminum Finish

The 4013TSTDALLH is a surface-mounted track door closer that installs on the pull side of left-handed doors. This LCN unit mounts to the top jamb with a parallel track arm configuration, providing controlled closing for high-traffic commercial openings that need reliable cycle performance. Track closers distribute opening forces across the door frame rather than concentrating stress at hinge points.

Built with forged steel main arm and double heat treated steel pinion, this Grade 1 closer handles heavy doors up to size 3 capacity. The cast iron body houses all-weather fluid that maintains consistent performance across temperature extremes. The 689 aluminum finish provides corrosion resistance for interior and exterior installations.
