PDQ 7100 Series: Extra Heavy-Duty Grade 1 Cast Iron Door Closers & Parts
The PDQ 7100 Series is an extra heavy-duty Grade 1 architectural door closer engineered for the most demanding, high-frequency environments. Featuring a high-strength cast iron body and a forged steel main arm, this series is designed to withstand the "brutal" conditions found in schools, universities, and military bases. A major advantage for facility managers is its LCN 4040 retrofit capability, utilizing the same mounting hole pattern to allow for a seamless, heavy-duty upgrade without the need for additional drilling or door modification.
PDQ 7100 Series
Built for maximum control and reliability, the PDQ 7100 Series features a full rack and pinion design with a large 1-1/2" diameter piston for smooth, consistent operation. This series offers an innovative spring design that includes an ADA-compliant 5 lb barrier-free setting plus six additional settings, providing 17% more adjustment capability than standard closers to find the "sweet spot" for any door. Backed by a 25-year limited warranty and a 3-hour UL fire rating, the 7100 Series is a fully featured door control solution that excels in high-traffic commercial and institutional applications.
