Global Door Controls TC4300CNS Series Door Closer in Aluminum (AL) finish is a heavy-duty institutional closer equipped with a Cushion Stop Arm (CNS) designed for parallel arm mounting. The cushion arm provides a controlled backcheck to prevent overextension of the door while maintaining full UL10C fire rating compliance, as it does not include a hold-open function.

Engineered for high-traffic commercial and architectural applications, the TC4300CNS-AL features a multi-size adjustable spring power range of sizes 1–6, ensuring precise tension adjustment for both interior and exterior doors. Certified to ANSI/BHMA A156.4 Grade 1 standards and UL Listed for positive pressure fire-rated openings, this closer provides reliable ADA barrier-free operation and long-term durability under demanding conditions.

Built with a heavy-duty aluminum alloy body and a full architectural cover, the TC4300CNS-AL delivers powerful performance and a clean, modern appearance. The Cushion Stop Arm absorbs door impact during opening and prevents structural damage in high-use environments such as schools, hospitals, and public facilities.
