LL, LR, C, and T Conduit Bodies: When to Use Each
Sep 28, 2026
LB gets most of the search traffic, but the rest of the Form 7 style family does the quiet work on commercial and industrial jobs. LL, LR, C, and T conduit bodies show up whenever the run turns, tees, or needs a straight pull through with access.
Conversions Tech stocks all five common configurations (LB, LL, LR, C, T) in UL Listed copper-free aluminum, NEMA 3R, trade sizes 1/2 inch through 2 inch. Threaded NPT serves rigid and IMC. Set-screw serves EMT. This article is a plain chooser for contractors, PAs, and counter staff.
Quick orientation
Think about where the cover opens relative to the direction of the conduits entering the body. That is the practical difference crews care about on a ladder.
- LB: Back opening relative to the run. Common 90 degree access pull.
- LL: Opening oriented for left side access on the turn.
- LR: Opening oriented for right side access on the turn.
- C: Straight through body for pull access on a continuous run.
- T: Tee configuration when a branch leaves the main run.
Always follow the engineer of record, the AHJ, and the listing instructions for fill, splicing, and supports. This page does not replace code.

Threaded versus set-screw (do not mix systems)
Threaded NPT bodies (675-300xx series language in our planning docs) join rigid and IMC raceway with threads. Set-screw bodies (677-300xx) clamp EMT. The wrong choice fails fit-up and wastes a truck roll.
Form 7 style crosses on threaded pages reference Crouse-Hinds, Appleton, and O-Z/Gedney Form 7 style lines. Set-screw pages reference Appleton E-series style numbers. Read the page you are buying.
When LL or LR shows up instead of LB
Prints and field bends do not always leave the cover where an LB expects it. LL and LR exist so the cover stays usable after the body is clocked into the rack. If a crew keeps fighting cover access on an LB, the type may be wrong rather than the brand.
Purchasing tip: match type first, size second, system third, cross fourth.
C and T without overthinking
C bodies give pull access on long straight segments where a pulling elbow is the wrong shape. T bodies create a branch path. Stock both if your shop supports commercial fit-out work. Conversions Tech includes C and T beside LB and the L turns so a single second source order can clear a shortage list.

FAQ
Can I substitute LL for LR if stock is short?
Only if the orientation still gives legal and practical cover access for that install. Type is not a casual swap. Check the print and the field condition.
Do C and T bodies use the same Form 7 style cross habit?
On threaded pages, yes: size for size Form 7 style crosses appear on the product page. Confirm the specific SKU.
Where do I apply for distributor or contractor trade pricing?
