B-Line Eaton series bolt on accessories, ANSI 61 gray polyester powder coated, Designed to be used with series filter kit, Steel, Louver plate size 4.

The LPK34 is a bolt-on louver plate kit that mounts to an enclosure to provide ventilation openings, and it is made to be used with the B-Line series filter kit so incoming air passes through a filter instead of straight into the box. It is a steel plate assembly in 16 gauge, not a fan or a blower, so you still need the filter kit (and any fan, if the design calls for one) to complete a vented enclosure.

Plan around the plate's stated dimensions of 8.125 in length/depth, 3.37 in height, and 3.12 in width. That is a small, narrow footprint, so it suits a single ventilation location on a panel or enclosure side rather than a full-height vent run. Lay the plate against the panel and confirm you have flat, unobstructed steel behind it before you drill for the bolt-on mounting.

The plate is finished in ANSI 61 gray polyester powder coat, which is the standard gray used across Eaton B-Line electrical enclosures and industrial panels. If your boxes are ANSI 61 gray, the plate will read as the same color family. If your enclosures are white, stainless, or a custom color, it will not match.

Order it as Eaton B-Line LPK34. That is the single model offered, so there is no separate finish or size selection to make on the order form.

Steel, in 16 gauge, with a polyester powder coat over it. That matters if you are venting an industrial or outdoor-rated enclosure where a molded plastic louver would not hold up to impact or to washdown and UV exposure the way coated steel does.
