Product Overview
The Appleton FSC-1-75 is a malleable iron FS-FD style cast device box, single gang, in the shallow FSC configuration, sized for 3/4 inch conduit. As the photos show, the FSC layout is a feed-through: one threaded 3/4 inch hub in each end, so the box sits in-line on a conduit run rather than dead-ending it. Interior capacity is 18 cubic inches per the cast marking, and the casting carries both the Appleton and O-Z/Gedney names, reflecting shared production within the same electrical group. FS-FD cast boxes are the workhorse housings for surface-mounted wiring devices on rigid conduit systems, valued for the durability of cast construction. This is clean, unused old stock from Appleton, a long-established name in electrical fittings.

Frequently Asked Questions
Is this box new?
Yes. It is unused new old stock, supplied in its original individual Appleton carton with the factory label intact.
What is a shallow FSC box?
It is a single gang cast device box in Appleton's FS-FD family, in the shallow depth, feed-through FSC configuration. The photos show the layout: a threaded 3/4 inch hub in each end and an 18 cubic inch interior.
What conduit size does it fit?
It is sized for 3/4 inch conduit, with the metric designator 21 cast beside the trade size on the body.
Is a cover or wiring device included?
No. You receive the cast box shown in the photos with its factory-installed green grounding screw; covers and wiring devices are not included.
How many are available?
We have 17 in stock as of this listing.
Why buy just the boxes you need here instead of a bulk lot on eBay or Amazon?
Because a two-box job should not require buying ten. PartsMine sells exact quantities, from a single box up to all 17. Shipping is $8 flat rate and free over $28, so one or two of these cast boxes typically beats the all-in price of a forced lot, shipped same or next business day from Idaho.
Malleable iron does not care about decades. Bolt this box into the run and it will still be doing its one quiet job long after the wiring inside has been pulled and replaced twice.
