B-LINE B129SS4 – Frequently Asked Questions
1) Is the B-Line B129SS4 splice plate stainless, and can I use it outdoors or in a wet area?
It is Type 304 stainless steel, which is the grade normally specified for outdoor, damp, and washdown work where plain electro-galvanized fittings would rust. For chloride exposure (coastal, pool chemical, heavy de-icing salt) Type 316 is the usual step up. Match the plate to Type 304 strut and Type 304 hardware so you are not mixing dissimilar metals at the joint.
2) Will a 1.62 inch wide splice plate sit flat on 1-5/8 inch strut?
Yes. At 1.62 inches wide the plate matches the 1-5/8 inch face width that standard strut channel uses, so it seats across the channel face without overhang. Its 3.5 inch length spans the joint far enough to put fasteners into both pieces of channel.
3) Is a two hole splice plate enough, or do I need a four hole splice?
Two holes, one into each length of channel, is the normal choice for a butt splice in a supported run where the joint is close to a hanger or anchor. If the splice lands in an unsupported mid-span and has to carry bending, a longer four hole plate or a channel-nested splice gives more fasteners and a stiffer joint. The B129SS4 is the two hole version at 3.5 inches long.
4) What is the exact part number to order this B-Line stainless splice plate?
Order Eaton B-Line model B129SS4. The SS4 suffix designates Type 304 stainless steel; it is a single-model item, so there are no finish or size options to pick.
5) Does the B129SS4 splice plate carry a UL listing or other certification?
No certification applies to this part. The B129SS4 is a structural strut fitting, and certifications are marked Not Applicable for it, so do not specify it where a drawing calls for a listed component.
