Designed as a replacement blade for Lufkin home and shop tape measure models requiring a B1-style blade with a 50-foot length and 0.375-inch width. Verify blade style and housing compatibility with the specific Lufkin model being serviced before installation.
Blade replacement should be performed by a qualified technician familiar with tape measure disassembly and reassembly procedures. Ensure the tape measure is fully retracted and tension is released before opening the housing. Follow the tool manufacturer's service documentation to avoid damage to the spring mechanism during blade swap. Dispose of worn blades safely, as the steel edges may remain sharp.
