LB17 to LB67 Conduit Body Cross Reference (Form 7 Style)
Sep 28, 2026
Electrical contractors and purchasing agents rarely type a house brand into a search bar when a job is moving. They type the number on the ticket. LB17, LB37, LB67, and the rest of the Form 7 style LB series are some of the most common strings in that habit.
Conversions Tech stocks rigid conduit bodies so you can match type and size, read the cross on the product page, and order when the usual bin is empty. This guide explains how LB Form 7 style numbers map in practice, what facts we publish on site, and how to avoid the wrong system (threaded versus set-screw).
What an LB conduit body is
An LB conduit body is a pull fitting with the cover opening on the back relative to the run. Crews use it when the raceway needs a 90 degree change with access for pulling and splicing within the rules of the install. On Form 7 style lines from brands such as Crouse-Hinds, Appleton, and O-Z/Gedney, LB numbers in the teens through sixties are a familiar shorthand for size steps from small trade sizes up through larger ones.
Conversions Tech sells LB bodies in trade sizes 1/2 inch through 2 inch as part of a wider set that also includes LL, LR, C, and T. Bodies are UL Listed copper-free aluminum and NEMA 3R rated. Threaded NPT versions serve rigid and IMC. Set-screw versions serve EMT.
We do not invent extra ratings beyond those facts. Confirm every cross on the live product page before you install.
How size for size Form 7 style crosses work on our site
Threaded rigid conduit bodies ship under the 675-300xx series language used in our catalog planning. Each product page carries size for size cross references to Crouse-Hinds Condulet, Appleton, and O-Z/Gedney Form 7 style lines, including LB17 to LB67 style references where they apply to that size.
That means the page is the source of truth. Marketing copy can teach the habit. The product page locks the match.
Practical workflow for a PA or foreman:
- Read the type on the ticket (LB).
- Read the trade size.
- Confirm threaded NPT for rigid or IMC versus set-screw for EMT.
- Open the matching Conversions Tech product and read the cross line.
- Check stock and shipping options. Same-day shipping on in-stock items when that option appears at checkout.

LB17, LB37, LB67 and why people search “equivalent”
Search phrases like “LB37 equivalent” mean the buyer wants a body that matches the Form 7 style size step they already trust, not a lecture about brand history. Conversions Tech answers that intent by putting the cross on the page and stocking aluminum NEMA 3R bodies in the 1/2 inch through 2 inch band.
Important limits:
- Cross reference is size for size Form 7 style guidance on the page. It is not a claim that every accessory, finish, or listing mark is identical to another manufacturer’s SKU.
- Explosion proof, hazloc, PVC coated, mogul, and other specialty forms are outside this line as described in our campaign facts.
- Set-screw EMT bodies use Appleton E-series style crosses on their own pages. Do not mix threaded Form 7 style habits onto EMT set-screw without checking the system.
Who this page is for
- Commercial and industrial electrical contractors, purchasing agents, and foremen who buy online when the supply house is out or slow.
- Distributors and supply houses that need a second source for the counter.
- Solar and EV installers, industrial maintenance, panel shops, and OEMs that pull standard LB configurations.
Supply houses are customers. Second source is the point.

If the ticket says LL, LR, C, or T instead of LB, stay in the same collection and filter by type. The same Form 7 style cross habit applies on threaded pages. See also our technical resources for type selection.
