Arlington Industries 4006 Adjustable Throat Liner for 2" Conduit Fittings

Arlington Industries 4006 Adjustable Throat Liner for 2" Conduit Fittings

The Arlington Industries 4006 Adjustable Throat Liner is a 2" trade size accessory built to protect conductor insulation as wires pass through the throat opening of a conduit fitting or connector. Designed with an adjustable, trimmable body, this liner lets electricians customize the fit to match the depth of the connector throat, delivering a smooth, protective surface for the 2" opening. It is intended for use alongside conduit fittings and connectors where sharp metal edges at the throat could otherwise nick or cut wire jacketing during and after conductor installation. By lining the throat of the fitting, the 4006 helps installers maintain conductor insulation integrity for the life of the electrical system, supporting cleaner, more reliable wire pulls on any job requiring a 2" connection.

Key Features

• Trade Size: 2" sizing matches the throat opening of corresponding 2" conduit fittings and connectors.
• Adjustable Construction: the liner can be trimmed and adjusted in the field to fit the specific depth of the connector throat.
• Insulation Protection: shields conductor insulation from sharp metal edges at the fitting throat, reducing the risk of nicks, cuts, or abrasion during and after wire pulls.
