GFCI Extension Cords

Keep personnel safe from electric shock with these cords. The industry desgination is SJTW, so the insulation resists water.

Cords with a 90° elbow plug fit flush against a wall outlet, so they fit behind machinery or in areas where space is tight.

Cords with automatic GFCI reset immediately regain power after ground is established.

Cords with manual GFCI reset prevent unexpected start-up.

Cord with a power-indicating light have a light on the socket that illuminates when the cord has power.

NEMA 5-15 Plug

Plug these cords into fans that have quick-disconnect terminals. The industry designation is SPT, so they have a flat cord shape.

Cords with a 90° elbow socket fit flush against the fan, so they fit in tight spaces.

Cords with a 45° elbow socket fit close against the fan.

Those with a temperature switch turn a fan on when the temperature reaches 88° F and off when it falls to 80° F. They are not adjustable.

Outlet Strips

Provide power to multiple devices with these outlet strips. A circuit breaker prevents damage from current overload and short circuits.

The face of 360° outlets rotate a full circle.

Surge suppression outlet strips protect against damage from voltage spikes. Surge rating indicates how much energy the outlet strip can absorb before it needs to be replaced; the higher the number, the better the protection.

Fasten mounting clips to a surface, and snap the channel on the back of outlet strips into the clips.

Controlled-Automatic-Wind Cord Reels

With One Outlet

With Two Outlets

With Four Outlets

NEMA 5-20 Plug

Controlled winding prevents the cord from whipping at the end, making winding safer and extending the life of the cord and reel. These reels also have a ratchet to hold the extension cord in place at any length; a quick pull releases the cord and the spring-driven winding mechanism retracts it. An adjustable ball lock controls how much cord retracts into the reel. They have an adjustable arm so the cord can be accessed from any position around the reel.

Reels with a circuit breaker prevent overload damage.
