The leading choice for low-voltage wire applications, the T25 staple is an absolute boss when installing garage door openers, thermostat wire, doorbell wire, alarm systems and much more. Also works great on computer, Cat5/Cat6. RG6/RG9, coax and phone cables. All Arrow T25 staples are made under strict quality controls at our Saddle Brook, NJ manufacturing plant.
