The HILLMAN FASTENERS RU1 is a key blank compatible with Russwin lock cylinders, sold in a 10-count bag for professional locksmiths and facilities maintenance personnel. This blank corresponds to Ilco number 1011 and carries the EZ number RU1, making it straightforward to cross-reference against existing inventory or service records. The blank is designed to be cut to match a customer key profile and fits into the standard Russwin keyway. At 0.3 pounds per bag, the package is lightweight and easy to store in a service van or shop cabinet.
This key blank is used in commercial and institutional settings where Russwin mortise or cylindrical locksets are installed. Locksmiths, building engineers, and facilities managers keeping key inventory on hand will find the 10-count bag a practical stocking quantity. For higher-volume applications, the product is available in a master carton of 50 bags. A minimum order of 10 blanks applies.
Designed as a replacement key blank for Russwin lock cylinders, cross-referenced as Ilco 1011. Specific compatible lock model numbers were not provided in the product data; verify keyway compatibility against the installed cylinder before cutting.
Key blank cutting should be performed by a qualified locksmith using a properly calibrated key duplicating machine. Verify that the blank seats fully and without play in the target cylinder before cutting. Always confirm the keyway profile matches the installed cylinder to avoid a wasted blank or a key that will not operate the lock.
