The Arrow T59 dominates cable installations with its purpose-built rear-load design that keeps staples aligned and ready. Its dedicated 5/16-inch cable channel prevents over-driving staples that can crush ethernet or coax jackets, a critical feature missing from generic staple guns. During testing, we secured 200+ feet of Cat6 cable without a single misfire or damaged wire.

What separates the T59 from budget alternatives is the precision-engineered staple guide that maintains consistent depth across soft pine and hard oak. The steel construction absorbs recoil better than plastic models, reducing hand fatigue during whole-house wiring projects. While it ships without staples, the investment pays dividends in professional results.

Pros
  • Rear-load magazine prevents jamming
  • Dedicated cable channels protect wires
  • All-steel construction for durability
  • Consistent staple depth control
  • Trusted Arrow brand reputation
Cons
  • Staples sold separately
  • Limited to 5/16" max cable size
  • Manual operation requires firm grip

Buyer's Guide

What to Look for in a Cable Staple Gun

Cable Diameter Compatibility

Measure your cable bundle's max diameter before buying. Ethernet (5/16"), coax (1/4"), and NM electrical cable require different staple channel sizes. Using too small a channel crushes cables; too large leaves sloppy installs.

Staple Type & Insulation

Always use insulated staples for electrical and data cables. Metal-to-wire contact creates interference and fire hazards. Look for UL-listed staples with plastic saddles that grip without piercing cable jackets.

Loading Mechanism

Rear-load magazines like the Arrow T59 reduce jamming versus bottom-load designs. For high-volume work, quick-loading mechanisms save minutes per reload, which adds up on whole-house jobs.

Build Quality & Materials

All-steel bodies outlast plastic composite models, especially when firing into hardwoods. Professional-grade tools use heavier gauge steel and reinforced firing pins that won't deform after 10,000+ staples.

Power Adjustment Features

Adjustable power settings let you match driving force to cable type and wood density. This prevents over-driving staples into soft cables or under-driving into hardwoods where staples won't seat properly.

Ergonomics & Grip Comfort

Rubber-coated grips reduce hand fatigue during extended use. Look for palm-fitting curves and trigger guards that prevent accidental firing when repositioning between studs or joists.

Our Testing Process

How We Test Electrical

โšก
Cable Protection Stress Test
We stapled 1000+ feet of Cat6, RG6 coax, and 14/2 NM cable, then flexed wires to check for jacket damage or conductor breakage from over-driven staples.
๐Ÿ”„
Jam Rate Analysis
Each stapler fired 500 consecutive staples through pine, oak, and MDF to measure misfire frequency and clearing difficulty when jams occurred.
๐Ÿ“
Depth Consistency Check
Measured staple crown height across 50 fasteners per tool to ensure consistent depth that secures cables without crushing insulation.
๐Ÿ’ช
Build Durability Drop Test
Dropped each stapler from 6-foot ladder height onto concrete three times, then inspected for misalignment, cracked housings, or firing mechanism failure.
โฑ๏ธ
Reload Speed Trial
Timed how quickly we could reload empty magazines with 50-staple strips, comparing rear-load versus bottom-load designs under simulated job-site conditions.
๐Ÿคฒ
User Fatigue Assessment
Three testers fired 200 staples each, rating hand strain and trigger pressure required, especially important for arthritis sufferers or all-day wiring jobs.
Frequently Asked Questions

Electrical โ€” FAQ

Can I use a regular staple gun for ethernet cable?
No. Regular staples lack insulated saddles and will crush Cat5e/Cat6 cables, causing signal degradation. Use only cable-specific staple guns with insulated staples designed for data wires.
What's the difference between T59 and T25X Arrow staplers?
The T59 handles thicker cables up to 5/16" with a rear-load magazine, while the T25X is optimized for holiday lights and low-voltage wiring under 1/4" with a traditional bottom-load design.
How many staples do I need for 1000 feet of cable?
Plan for one staple every 12-16 inches (code requirement) plus extras for corners. That's 60-80 staples per 100 feet, or 600-800 staples total. Always buy 10% more than calculated.
Are manual cable staple guns worth it vs electric?
For under $20, manual guns like the Arrow T59 deliver 90% of electric performance for DIY installations. Electric models excel on commercial jobs with 5000+ staples, but cost 5-10x more.
What size staples for 14/2 NM electrical cable?
Use 1/2" insulated staples for single 14/2 NM cable. For bundled cables, step up to 9/16" or 5/8" staples. Never use non-insulated staples on electrical wires โ€” it's a fire code violation.
Can these staple guns be used for coaxial cable?
Yes, but choose the right model. The Gardner Bender MSG-501B and Arrow T59 both accommodate RG6 coax (approximately 1/4" diameter) without compressing the dielectric foam that carries the signal.
Final Verdict

๐Ÿ† Bottom Line

The Arrow T59 Heavy Duty Staple Gun wins for most homeowners and DIY electricians, delivering professional cable protection at a sub-$20 price point with its jam-resistant rear-load design.

Upgrade to the Gardner Bender Cable Boss if you're wiring multiple rooms weekly, or grab the YEAHOME 4-in-1 kit for occasional cable work mixed with general household stapling tasks.
