Thomas & Betts 680F Form 8 2" Iron Conduit Body Replacement Cover & Gasket

The Thomas & Betts 680F is a Form 8 replacement cover and gasket set engineered for 2" iron conduit bodies used in commercial and industrial electrical systems. Built from rugged iron, this cover restores a secure, properly seated closure to Form 8 conduit body enclosures without requiring replacement of the entire fitting. Iron conduit bodies are widely used in exposed and surface-mounted conduit runs where a durable, standardized cover style is needed for long-term serviceability, and the 680F is sized to match that Form 8 profile. The included gasket seats against the conduit body opening to help maintain a tight closure between the cover and body. Designed as a direct-fit replacement part, the 680F simplifies maintenance on existing Thomas & Betts iron conduit body installations by letting installers renew the cover and gasket without disturbing the wiring or the conduit body itself.

Key Features

  • Trade Size: 2" cover sized to fit compatible Form 8 iron conduit bodies.
  • Durable Construction: Solid iron cover plate built to withstand the demands of commercial and industrial electrical enclosures.
  • Form 8 Configuration: Matches the Form 8 conduit body profile for proper alignment and a secure seated fit.
  • Replacement Cover & Gasket: Ships with both the iron cover plate and a matching gasket, so the full closure assembly can be renewed with a single part.
  • Sealing Gasket: The included gasket seats between the cover and the conduit body opening to help maintain a snug closure.
  • Direct-Fit Replacement: Designed specifically for the 680F Form 8 cover position for straightforward field replacement.
  • Maintenance-Friendly: Allows replacement of a worn, damaged, or missing cover and gasket without swapping out the entire iron conduit body.

Thomas & Betts TB280F – Frequently Asked Questions

1) Which trade sizes does the Thomas & Betts Form 8 conduit body cover come in?
Two sizes: a 3/4 inch cover, part number 280F, and a 2 inch cover, part number 680F. Match the cover to the trade size of the conduit body already on the run, not to the wire fill. Both ship as a cover plate with a gasket.
2) Do I have to replace the whole LB or T fitting if the cover is missing or the gasket is shot?
No, that is the point of the 680F and 280F. They renew the closure assembly on an existing iron Form 8 conduit body, so you leave the body and the conductors in place and only swap the cover plate and gasket. Useful on surface-run conduit where pulling the body would mean cutting into the raceway.
3) Will a Crouse-Hinds 270 cover fit a Form 8 iron conduit body?
No. The Crouse-Hinds 270 is a Form 7 wedge nut cover made of sheet steel, so it is cut to the Form 7 profile. The Thomas & Betts 680F is a Form 8 cover and gasket set sized for 2 inch iron conduit bodies, and it matches the Form 8 body profile for proper alignment and a seated fit. Form 7 and Form 8 covers are not interchangeable, so match the form number stamped on the conduit body before ordering.
4) Can I use the 280F or 680F cover on a non-metallic (PVC) conduit body?
These are iron covers cut to the Form 8 iron body profile, so they are intended for Thomas & Betts iron conduit bodies. For a non-metallic body, use the cover and gasket made for that body line, such as the Arlington AnyBODY series cover and gasket.
5) What is the difference in cover material between the Thomas & Betts 680F and the Crouse-Hinds 270?
The Thomas & Betts 680F is a solid iron cover plate shipped with a matching gasket, built for commercial and industrial conduit body enclosures. The Crouse-Hinds 270 is a sheet steel wedge nut cover. The 680F is a cast iron plate intended to renew the closure on an existing iron conduit body without disturbing the wiring, while the 270 uses the wedge nut retention style of the Form 7 line.
6) Can I replace just the cover, or do I need a whole new conduit body?
If the body itself is sound, a cover and gasket set is enough. The Thomas & Betts Form 8 cover and gasket is a direct-fit replacement that renews a worn, damaged, or missing cover without swapping out the iron conduit body or disturbing the wiring. Cover-and-gasket sets are sold the same way by other makers - the Arlington Industries 933 AnyBODY is a 1-1/4 inch LB cover and gasket set, for instance - so the decision comes down to matching the body profile and trade size you already have in the run.
7) What material are these Form 8 conduit body covers made of?
Solid iron, matching the iron conduit bodies they close. That is heavier than the sheet steel used on some competing covers (the Crouse-Hinds 270 Form 7, for example, is sheet steel) and is intended for exposed and surface-mounted commercial and industrial runs.
