Thomas & Betts ASLB-2 Service Entrance Body, Cover & Gasket

The ASLB-2 is sold each, but it ships on an order multiple of 10. Inner package is 10 pieces and the outer carton holds 50, so plan quantities in tens. Each unit weighs 0.28 lbs.

The throat is smooth for wire pulling, which is the point of using a conduit body instead of forcing a bend. Usable volume is published at 3 cubic inches, so check your conductor count and size against that figure before committing, heavy service conductors can outrun a small body.

No, they are different fittings that do different jobs. The ASLB-2 is a service entrance body with cover and gasket, made of die cast aluminum, that mounts flush to the wall and gives you an access point with a smooth throat for pulling conductors. The Cantex 5133671 is a PVC service entrance head, also called a weatherhead, which caps the top of the riser and keeps water out where the conductors exit. On a typical service riser you may need both: the head at the top and a body like the ASLB-2 where the run turns into the wall.

Die cast aluminum, with retained deep slotted stainless steel cover screws. The stainless screws are the detail that matters on an exterior service entrance, they are the part that normally seizes or rusts solid when a body has to be opened years later. It is also RoHS compliant.

It mounts flush to the wall, so there is no standoff bracket to allow for. The body's published dimensions are 3-15/16, 3-1/4, 1-1/2, 1-3/8 and 1-3/4 inches across its A through E measurements, so lay out the opening and any adjacent fittings against those figures.

Body, cover and gasket all come together under the single part number ASLB-2. Nothing additional is needed to close the fitting up, the cover screws are included and retained in the cover so they do not drop out on a ladder.

The Thomas & Betts ASLB-2 body is die cast aluminum, so if your installation calls for a non-metallic fitting it is not the match. The Cantex 5133671 is a PVC service entrance head from the Cantex 5 Series, which gives you a non-metallic option at the top of the riser. Keep in mind the Cantex part is a weatherhead rather than a conduit body with a removable cover and gasket, so confirm which function the opening actually needs before you swap.

The Thomas & Betts ASLB-2 is built for rigid and IMC conduit and is UL listed, with retained deep slotted stainless steel cover screws so the cover screws stay with the body during service work. Its die cast aluminum body suits a metallic raceway run. The Cantex 5133671 service entrance head is a PVC fitting from the Cantex 5 Series and is oriented toward non-metallic raceway, so for a rigid or IMC run the ASLB-2 is the fitting that follows the raceway type.
