Designed with a universal arm and featuring thru-bolts, this surface door closer is engineered to meet the rigorous demands of architects and building owners alike. The 281 Series boasts ANSI/BHMA Grade 1 certification, ensuring durability and reliability with a 10-year warranty. This versatile closer accommodates a range of mounting applications, including standard, top jamb, parallel, and track installations. Equipped with adjustable spring power, it offers a size range from 1 to 6, factory-set to size 3 for convenience. Notably, it conforms to UL10C and UBC standards for positive pressure fire tests, making it suitable for fire-rated doors, although modifications should be consulted with a code specialist. Constructed from high-impact, non-corrosive materials and available with an optional metal cover, the closer is built to withstand the elements, thanks to all-weather fluid that ensures operational efficiency in extreme temperatures.
