The Arrow T59 Insulated Staple 1/4″ Clear solves the cable protection problem that bare metal staples can’t touch. The clear plastic coating prevents electrical contact and cable abrasion while remaining virtually invisible after installation. At 18-gauge width with a 1/4-inch length, these staples handle cables up to 5/16 inch (8 mm) diameter — perfect for CAT5, CAT6, coaxial, and low-voltage power cables.
Skip it if you’re using standard nail-on clips or don’t mind visible fasteners. This product shines when you need clean cable runs that won’t fail inspection, especially on walls, studs, joists, and ceilings where the wide crown design spreads the load to prevent cable damage.
Cable Compatibility and Installation Precision
The 5/16 inch (8 mm) cable capacity covers most residential and commercial wiring needs. That’s enough for standard ethernet runs, coax drops, and even some bundled low-voltage cables. The wide crown design matters here — it distributes pressure across more cable surface than narrow staples, reducing the chance of crushing the internal conductors.
The clear insulated coating protects cables from abrasion and electrical contact while staying nearly invisible against most surfaces. Unlike black plastic staples that scream “cable here,” these blend into the installation. The coating also prevents the steel core from cutting into cable jackets during temperature cycling — a real concern in Montana where materials expand and contract with 100-degree annual temperature swings.
| Specification | Value |
|---|---|
| Cable Capacity | Up to 5/16” (8 mm) diameter |
| Compatible Cables | CAT5, CAT6, RG5, RG6, low-voltage power |
| Crown Width | 1/4” (6 mm) |
| Leg Length | 1/4” (6 mm) |
| Wire Gauge | 18 GA wide-crown |
| Pack Size | 300 staples per box |
The corrosion-resistant steel construction suits both indoor and outdoor use. That matters for exterior cable runs or damp crawl spaces where standard staples would rust and fail.
Tool Requirements and Professional Results
These aren’t hammer-in staples. You must use an Arrow T59 or compatible T59-style staple gun. The 18 GA wide-crown specification means generic cable staplers won’t work — you need the specific tool designed for insulated staples.
Installation guidance emphasizes avoiding over-driving staples to prevent crushing the cable core. The right tool makes this easier to control than hammering. Professional electricians appreciate the fast and consistent application with T59 staple guns compared to individual clips or straps.
The staples work with data and communication cables like ethernet, coaxial cables for TV and satellite, low-voltage power cables, and various alarm and intercom wiring. The wide crown design provides strong holding power for these applications.
The Bottom Line
Arrow T59 Insulated Staples deliver what low-voltage installers need — secure cable management that won’t damage wires or look sloppy. The clear coating vanishes on most surfaces while protecting cables from both mechanical damage and electrical contact. At 300 staples per box, you get enough for typical residential jobs without buying bulk.
The requirement for T59-compatible tools might seem limiting, but it ensures consistent, professional results. These staples earn their place in any low-voltage installer’s kit, especially for visible cable runs where appearance matters as much as function.
Frequently Asked Questions
What size cables work with Arrow T59 1/4” staples? These staples accept cables up to 5/16 inch (8 mm) in diameter, which covers CAT5, CAT6, RG5, RG6, and most low-voltage power cables. Measure your cable diameter first — forcing oversized cables risks damage.
Does this product require a special tool? Yes. These require an Arrow T59 Insulated Cable Staple Gun or any generic T59-style staple gun. Regular staplers and nail guns won’t work with 18 GA wide-crown insulated staples.
Can these staples handle outdoor installations? The corrosion-resistant steel construction is suitable for both indoor and outdoor use. The clear coating adds protection against moisture, making them viable for exterior cable runs or damp locations.
How many staples come in a box? Standard packaging includes 300 staples per box. Bulk options are available for larger projects.
What’s the actual crown width on these staples? The crown width is 1/4 inch (6 mm), which provides the wide profile needed to distribute pressure and prevent cable damage during installation.
