Apex OC129012SF59N Replacement Tape Measure Blade 18 Ft

Product Description

The APEX OC129012SF59N is a replacement blade designed for Atlas Chrome Clad and Nubian Double Duty tape measures. This blade spans 18 feet in length with a D4 blade style and measures 0.5 inches wide, making it a direct-fit service part for technicians and tradespeople who rely on these measure housings daily. Rather than replacing the entire tape measure unit, a worn or kinked blade can be swapped out, restoring the tool to working condition. At 0.5 pounds, the blade ships as a single unit and fits into the existing housing without modification to the casing.

This replacement blade is suited for trade professionals across HVAC, plumbing, electrical, and general mechanical service work where precise linear measurement is a routine requirement. It fits the Atlas tape measure family, including Chrome Clad and Nubian Double Duty housings. The D4 blade style designation identifies the specific geometry and locking mechanism compatibility within that product family. Service technicians who carry Atlas-brand tape measures as part of their standard toolkit will find this blade a practical stocking spare.

Installation Notes

Blade replacement on tape measure housings is typically performed by hand tools without specialized equipment. Refer to the housing manufacturer instructions before disassembling the case, as internal spring tension requires careful handling. Ensure the blade is fully seated and the locking tab is engaged before returning the tool to service. Blade replacement does not require any electrical shutoff or gas isolation procedures.
