Thomas & Betts BLB-1 – Frequently Asked Questions

1) What trade sizes does the Thomas & Betts BLB conduit body come in?
Two sizes: BLB-1 for 1/2 inch trade size and BLB-2 for 3/4 inch. Both are Type LB die cast aluminum bodies, so pick the one matching the EMT or rigid run feeding the opening.
2) Do I have to order the cover and gasket separately for a BLB-1?
No. The BLB-1 ships with covers and gaskets. The matching parts are the CV-1 die cast cover or SCV-1 stamped aluminum cover, with a GKV-1 composition gasket or GKN-1 neoprene gasket, so you can also reorder a replacement by those numbers later.
3) Can an Arlington 935NM be used instead of a BLB-1 on a 1/2 inch conduit run?
No. The Arlington 935NM AnyBODY LB-style body is a 2 inch threadless conduit body, so it will not land on a 1/2 inch raceway. The Thomas & Betts BLB-1 is the 1/2 inch trade size Type LB body, with BLB-2 covering 3/4 inch. For small-trade-size LB work, stay with the BLB sizes; the 935NM is the choice when the run is 2 inch.
4) What is the difference between the Thomas & Betts BLB conduit body and the Arlington 935NM AnyBODY LB-style body?
They are both LB-style conduit bodies, but they differ in material, connection method, and size. The Thomas & Betts BLB is a Type LB conduit body in die cast aluminum, offered in 1/2 inch (BLB-1) and 3/4 inch (BLB-2) trade sizes with threaded hubs for EMT-system work. The Arlington 935NM is a non-metallic LB-style body in 2 inch trade size with a threadless connection. If the raceway run is 1/2 inch or 3/4 inch metallic conduit and you want a metal body that bonds through the hubs, the BLB is the one that fits; the 935NM covers a 2 inch opening and a non-metallic, threadless approach.
5) How many conductors can I splice inside a 1/2 inch BLB-1?
The BLB-1 chamber is 4.3 cubic inches. Use that figure against the NEC box fill allowance per conductor size for your job to confirm the count, since fill is driven by wire gauge, not by the body itself.
6) Can I buy just one BLB conduit body, or is there a minimum?
Sold each, but the order multiple is 10. Inner packs are 10 pieces and the outer carton holds 50, so quantities come in increments of ten.
7) Will a die cast aluminum conduit body hold up outdoors or in a damp location?
Die cast aluminum is corrosion resistant, and the body takes a gasketed cover (composition GKV-1 or neoprene GKN-1) with retained stainless steel screws for sealing. Neoprene is the choice where you want a more weather-resistant seal. Aluminum should not be buried in concrete or set in direct contact with masonry or soil without protection.
8) What is the difference between a metal BLB body and a non-metallic LB body?
The BLB is die cast aluminum, which carries equipment bonding through the raceway and takes a gasketed metal cover. The Arlington 935NM AnyBODY is non-metallic and threadless, which suits PVC systems and corrosive environments but needs a separate bonding path for metal raceway. Size also separates them: the BLB covers 1/2 and 3/4 inch, the 935NM is 2 inch.
9) I need a non-metallic LB body for a corrosive area - is the Thomas & Betts BLB the right pick?
The BLB is die cast aluminum, so it is a metallic body. Where the specification calls for a non-metallic LB body, the Arlington 935NM AnyBODY is the LB-style option built as non-metallic. Note the size difference before you order: the 935NM is a 2 inch threadless body, while the BLB is made in 1/2 inch and 3/4 inch trade sizes.
10) Does the BLB come with a cover and gasket, or do I order those separately like some LB bodies?
The Thomas & Betts BLB is supplied with cover and gasket options rather than as a bare body: a die cast cover (CV-1) or stamped aluminum cover (SCV-1), with a composition gasket (GKV-1) or neoprene gasket (GKN-1) for the 1/2 inch BLB-1. That differs in approach from the Arlington 935NM AnyBODY, which is a non-metallic LB-style threadless body in 2 inch. If you are standardizing cover and gasket part numbers across a facility, the BLB's CV/SCV and GKV/GKN numbers are the ones to put on the MRO list.
11) Is the BLB conduit body RoHS compliant for a government or institutional spec?
Yes, the BLB die cast aluminum conduit body is RoHS compliant, and it is UL certified.
12) What are the outside dimensions of the 1/2 inch BLB-1 conduit body?
The BLB-1 measures 3-7/8 (A), 4-9/32 (B), 1-5/16 (C), 1-5/16 (D), 3-1/2 (E) and 2-1/16 (F) inches per the manufacturer's dimension letters. Check the C and D figures if you are fitting it into a tight chase or behind trim.
