Treely’s™ custom hardware prep offers tailored solutions for those seeking specifications beyond the standard. This can include accommodating a full mortise lock body, adjusting bore sizes to fit narrow backplate hardware or incorporating features such as a T-strike.

Precision in custom hardware prep is essential, considering that hardware manufacturers provide products in diverse sizes and specifications unique to their brand. Ensuring accurate information gathering and meticulous execution of the door’s hardware prep is crucial for a successful installation and the door’s optimal performance for the life of the product.

The starting point is the manufacturer’s specifications. While some brands offer comprehensive and detailed specs, others may not. Begin by submitting the manufacturer’s specifications to Treely™, and if additional information is required, we’ll work with you to ensure accuracy in gathering all the necessary details.
