Bushings

A bushing is a sleeve that protects an electric cable when it passes through a panel. A bushing is an insulated device that allows an electrical conductor to pass safely through an (usually) earthed conducting barrier such as the wall of a transformer or circuit breaker.

Anti-Short Bushings
Anti-Short Bushings are used in the terminations of flexible metal conduit and armored cables. They can be inserted into the inside diameter of each termination point to protect the conductors from the sharp edges of the raceway where cut.

EMT Insulated Push On Bushings
The EMT Insulated Push On Bushings are constructed of white nylon for durability. It can be used in air handling spaces per the NEC code. It comes in a variety of sizes from ½” to 4” in diameter for a variety of applications. It can also be used for rigid, IMC, and PVC rigid conduit for the same protective purposes.

Grounding Bushings
Grounding Bushings have a specification grade that provide a grounding lug to allow for grounding of conduit through the insulated bushing. Grounding Bushings provide a grounding lug to allow for grounding of conduit through the insulated bushing. They help to protect insulated conductors from abrasion during pulling or due to mechanical vibration.

Insuliner Sleeve/Adjustable Throat Liner
Insuliner Sleeves and Adjustable Throat Liners are meant to be installed in fittings after conduit, fitting and wire are in place. It allows for installation to meet local electrical code. It is non-metallic.

Knockout Bushings
Knockout Bushings are designed to protect wires in threaded rigid or IMC conduits. They are made of heat-tolerant thermoplastic and they can be used in indoor or outdoor environments. They protect wires in threaded rigid or IMC conduits. They are UL and CSA listed.

Plastic Insulated Bushings
Plastic Insulated Bushings are for use on threaded Rigid/IMC conduit. The bushings provide a smoothly rounded surface at the entrance of raceways. The insulated bushings are made of high impact polypropylene that is temperature rated at 105° C.

Reducing Bushings
Reducer Bushings are used to connect conduit and that has one size thread to another conduit with a different size thread. There are steel, nylon and zinc plated steel bushings and washers that come in a wide range of sizes to fit whatever conduit reducing need you have.
