Gardner Bender MSB1540 Steel Wire Staple 1/8x5/8 in 40-pk

Product Description

The GARDNER BENDER MSB1540 is a steel fiber insulated wire staple designed to secure and protect low-voltage wiring in residential and light commercial applications. Each staple features a steel body with a fiber insulating cradle that keeps wire from direct metal contact, reducing the risk of insulation damage during installation. Sold in a 40-count package, the MSB1540 measures 1/8 inch by 5/8 inch and is suited for fast, repeated fastening along framing, trim, and finished surfaces. Electricians and low-voltage technicians reach for these when routing wiring neatly and code-consciously.

The MSB1540 is used in residential and light commercial wiring runs for bell wire, speaker wire, thermostat wire, telephone wire, and similar low-voltage conductors. The fiber insulator cradles the wire to prevent pinching or chafing at the fastener point, which is especially important when stapling signal and control wiring where conductor integrity directly affects system performance. These staples are a standard consumable on low-voltage rough-in and finish work.

Key Features

• Steel construction for secure, lasting fastening in wood framing and trim
• Fiber insulating cradle protects wire insulation from direct metal contact
• 1/8 inch by 5/8 inch size suits common low-voltage wire gauges

Compatibility

Designed for use with bell wire, speaker wire, thermostat wire, and telephone wiring; suitable for general low-voltage wire stapling applications in residential and light commercial installations.

Installation Notes

Low-voltage technicians and electricians install these staples using a standard staple hammer or hand stapler rated for the fastener size. Before stapling any wiring, confirm power is removed from connected circuits. Drive staples snug against the wire without compressing the conductor or deforming the insulation. Follow NEC guidelines for securing and supporting low-voltage conductors along framing and finished surfaces.
