Norton Rixson 51 Series Shallow Depth Floor Closer - 3/4" Offset Hung Shallow Closer
The Norton Rixson 51 Series Shallow Depth Floor Closer is a high-performance 3/4" offset hung closer specifically engineered for installations with limited floor depth. Despite its compact size, this closer provides the same strength, reliability, and door control as standard-depth models, making it ideal for projects where slab thickness is restricted.
Constructed from heavy-duty cast iron and equipped with precision-adjustable controls, the 51 Series delivers smooth, consistent door operation while maintaining a clean, concealed architectural appearance. It is the perfect choice for commercial and institutional facilities that demand durability, space efficiency, and aesthetic design integration.
