Apex Tool Group O1290SF590N 25 Ft D4 Replacement Blade

Product Description

The APEX TOOL GROUP O1290SF590N is a replacement tape measure blade engineered for the Atlas Nubian tape measure line. The blade measures 25 feet in length and features a D4 blade style, making it a direct service part for restoring a worn or damaged tape to working condition. At 0.5 inches wide, the blade is sized for standard tape housing compatibility. Licensed HVAC technicians, plumbers, electricians, and general contractors rely on precision measuring tools daily, and this replacement blade extends the service life of an existing tool rather than requiring a full unit replacement.

This blade is intended for use with Atlas Nubian tape measure housings that accept the D4 blade profile. It is suited for residential and commercial trade environments where layout, rough-in measurements, and material cuts demand a reliable, full-length 25-foot blade. The overall installed dimensions of the blade cartridge are 5.7 inches in length, 4.6 inches in width, and 1.3 inches in height, confirming fit within compatible housings before ordering.
