These are the Arrow T50 5/16" staples, which provide slightly more depth and holding power than the 1/4" version for your heavy-duty projects.

• Design & Utility: These high-carbon steel staples are the "middle ground" in your T50 inventory. The 5/16" leg length is perfect for tasks such as installing wire mesh, light trim, or upholstery where a 1/4" staple is too short but a 3/8" or 1/2" would be overkill.

• Bulk Configuration: Similar to your previous entry, these come in packs of 1,250 staples with 4 packs per box, giving you a total of 5,000 staples to ensure you don't run out during large-scale work like insulation or vapor barrier installation.

• Compatibility: Designed for full compatibility with your Arrow T50 Heavy Duty Staple Gun.
