Thomas & Betts SS-B – Frequently Asked Questions

1) Will the Thomas & Betts SS-B cover fit a 4-inch round or octagon box?
The SS-B is a round/octagon box cover measuring 4 1/8 inches in diameter, which is the standard overlap size for 4-inch round and 4-inch octagon boxes. The slight oversize is what lets it cover the box lip rather than sit inside it.
2) Is the SS-B cover rain tight for an outdoor electrical device?
Rain tight performance comes with a condition: the SS-B is rated rain tight when installed on compatible Red Dot boxes. Mount it on anything else and you should not count on the weather seal. The stamped aluminum body itself resists corrosion outdoors.
3) Do I have to buy Thomas & Betts SS-B covers in a case, or can I order a few?
Sold each, but ordered in multiples of 15. Inner pack is 15 covers and the full carton holds 90, so a single piece order will not go through; plan quantities in 15s.
4) What is the difference between the Thomas & Betts SS-B cover and the RACO 894KH round cover for octagon boxes?
The Thomas & Betts SS-B is a stamped aluminum round/octagon box cover measuring 4 1/8 inches in diameter in a silver finish, used as a device box cover with rain tight performance when paired with compatible Red Dot boxes. The RACO 894KH is a KWIK-HANG Series 4 inch round swivel cover for octagon boxes - the swivel design is intended for fixture hanging rather than weather sealing a device opening. Choose the SS-B when the opening is an outdoor device box and the 894KH when you need a swivel-style octagon cover.
5) Is the SS-B a blank cover or does it have device openings?
It is a device box cover, not a blank. It is built to close out a box with a wiring device installed, so it is not the part to use if you simply need to seal an unused box.
6) Does the SS-B cover meet RoHS requirements for a government or institutional spec?
Yes, the SS-B is RoHS compliant, and it is a UL listed cover. Those are the two compliance points stated for it, which covers most institutional submittal checklists for a box cover.
7) Is the Mulberry 11700 blank cover a substitute for the Thomas & Betts SS-B?
They are not interchangeable in intent. The Mulberry 11700 is an F-35 Series galvanized steel oval/round blank cover with a 3/4-inch provision, so it closes off a box rather than serving a device. The Thomas & Betts SS-B is a stamped aluminum device box cover, 4 1/8 inches in diameter, that provides rain tight protection with compatible Red Dot boxes. Use the Mulberry 11700 where the box is being blanked off and the SS-B where a device is being covered.
8) I need a corrosion-resistant cover rather than steel - which should I specify?
The Thomas & Betts SS-B is stamped aluminum with a silver finish, which is the choice where corrosion resistance matters on an exterior device box. The Mulberry 11700 F-35 Series cover is galvanized steel, a different material approach for round and oval openings. Both are round-style covers; the material is the deciding factor for the environment you are installing into.
9) Will aluminum covers corrode where I have steel boxes or coastal exposure?
The SS-B is stamped aluminum with a silver finish, which holds up against corrosion in damp and outdoor service. If your installed boxes are galvanized steel and you would rather match metals, a galvanized steel cover like the Mulberry F-35 Series is the like-for-like material, though it is a blank rather than a device cover.
10) Can I order the SS-B in a different finish or size?
One configuration only: model SS-B, 4 1/8 inch diameter, silver stamped aluminum. There is no finish or diameter option to specify on the order.
