Red Dot S105E-R – Frequently Asked Questions
1) Can the Red Dot S105E-R box be used outdoors in the rain?
Yes. The S105E-R is a Dry-tite weatherproof box, rated for use in dry, damp and wet locations, so it holds up outdoors on exterior walls, posts and equipment pads. The cover edges are machined clean so the gasket seats evenly and seals the device opening.
2) What size conduit does the Red Dot S105E-R rectangular box take, and how many hubs?
Three 3/4 inch threaded hole openings. That gives you a feed in, a feed out, and a third for a branch or drop without adding a second body, which is why it is the common pick when a run has to continue past the device.
3) Is an 18.3 cubic inch weatherproof box big enough for two devices?
The S105E-R holds 18.3 cubic inches, which is single-gang rectangular volume. Fill calculations govern how many conductors and devices you can put in it, and at 18.3 cubic inches it is sized for one wiring device plus the conductors and grounds for a 3/4 inch three-way run, not a two-gang assembly. For two devices, step up to a two-gang weatherproof box.
4) Does the Red Dot S105E-R come with a cover and gasket?
No. The S105E-R is sold as the box alone, one each, in silver. The cover and its gasket are ordered separately, chosen to suit the device going in (blank, duplex receptacle, GFCI or toggle switch). Order the cover with the box so the opening does not sit exposed on the job.
5) Will the S105E-R protect a terminal block or small electronic component, not just a receptacle?
Yes. The Dry-tite line is built to protect wiring devices, switches, electronic components and terminal blocks, so using the S105E-R as a small junction or terminal enclosure on a damp or wet-location circuit is within its intended use. With 18.3 cubic inches you have room for a compact block and the conductors feeding it.
6) What is the exact part number for the Red Dot 3-hole 3/4 inch silver rectangular box?
Red Dot S105E-R. That is the manufacturer part number, not a house code, so it cross-references cleanly on a distributor order or a submittal. It is the silver three-hole 3/4 inch rectangular weatherproof body.
7) Should I use a 3-hole box or a 2-hole weatherproof box for an exterior receptacle?
It comes down to where the box sits in the run. A two-hole body handles a straight-through feed. The three-hole S105E-R adds a third 3/4 inch opening, so a box at a corner, a tee, or a point where a branch drops to another device can be served with one body instead of a box plus a condulet. Unused hubs get plugged. On an end-of-run device, the extra hole is simply one more plug to buy.
8) Will the Red Dot S105E-R match the other weatherproof boxes already on my building?
The S105E-R is finished in silver, the standard Red Dot Dry-tite look, so it blends with existing silver Red Dot bodies on the same elevation. If your other openings are bronze or white covers, the covers can be swapped without changing the box, since covers order separately from the body.
9) Where is the Red Dot S105E-R manufactured?
India. That matters on public and institutional work where country of origin has to be declared on the submittal, so note it before it goes on a government or federally funded project.
