Yes. The ASA-37-300HNSS4 sleeve anchor is rated for both solid and hollow core base materials, which is what separates a sleeve type expansion anchor from a wedge anchor. The expansion sleeve grips over a longer bearing area, so it holds in hollow CMU and brick where a wedge anchor would spin or pull. Good for strut, conduit hangers, and equipment bases mounted to block walls.

It is a 3/8 inch by 3 inch sleeve anchor. Sleeve anchors are drilled to the nominal anchor diameter, so a 3/8 inch carbide bit gives the correct hole, drilled deeper than the embedment to clear dust. The 3 inch length covers the fixture thickness plus embedment, so account for your strut or bracket thickness when you check you have enough anchor left in the concrete.

The ASA-37-300HNSS4 is type 304 stainless steel, so it suits exterior walls, parking structures, wash-down areas, and damp mechanical rooms where a zinc plated anchor would bleed rust. Type 304 is the general purpose austenitic grade; for coastal or chloride heavy exposure specifiers usually step up to 316.

Yes, it carries a UL Listing. That matters on electrical work where the inspector wants listed support components for conduit racks, cable tray, and strut hung from concrete or masonry.

Use the sleeve type for hollow block. A wedge anchor needs solid, uncracked concrete to expand against and it will not develop load in a hollow CMU cell. The B-Line ASA-37-300HNSS4 is a sleeve type expansion anchor rated for solid and hollow core material, so one part covers a wall that is part poured concrete and part block. In solid concrete only, either style works.

Order ASA-37-300HNSS4. In that designation the 37 is the 3/8 inch diameter, 300 is the 3 inch length, HN is the hex nut head style, and SS4 is type 304 stainless.

It is a hex nut style sleeve anchor, so the nut and washer are part of the assembly and the anchor sets by tightening that nut. You do not order separate hardware. Set it through the fixture, tighten to draw the cone into the sleeve, and the fixture is clamped in one step.
