Apex OCN1291SF590N Replacement Blade 33 Ft D1

Product Description

The APEX OCN1291SF590N is a replacement tape measure blade engineered for use with Atlas Chrome Clad and Nubian Double Duty tape measure housings. The blade spans 33 feet in length and measures 0.5 inches wide, following a D1 blade style profile. At 0.8 pounds and a compact 5.4-inch overall length, this replacement blade allows technicians and tradespeople to restore a worn or damaged tape measure to full working condition rather than replacing the entire tool. It is sold individually and is appropriate for any trade professional who relies on accurate linear measurement on the job.

This blade is suited for use in residential and commercial construction, mechanical trades, and general contracting environments where a 33-foot measuring range is required. The D1 blade style is a standard profile compatible with Atlas-family housings. Tradespeople performing HVAC rough-in, plumbing layout, electrical conduit runs, or structural framing will find the 33-foot reach practical for both short and extended measurements without repositioning.

• 0.5-inch blade width provides a balance of rigidity and compact retraction

Compatibility

Installation Notes

Blade replacement on tape measure housings should be performed by following the housing manufacturer's disassembly procedure with the spring tension fully released before opening the case. Use appropriate screwdrivers or housing-specific tools to avoid damaging the case or spring mechanism. Take care when handling the retraction spring, as stored tension can cause injury if released suddenly. Verify the blade seats correctly in the spool and the hook end is properly secured before returning the housing to service.
