Carlon E987R – Frequently Asked Questions

1) What size is the Carlon E987R junction box, and how much splicing room does it give me?
The E987R measures 6 x 6 x 4 inches, which is a lot more interior volume than a standard 4 inch square box. That depth makes it practical for multi-conductor splices, taps, and terminations where you need room for wire nuts and slack rather than just a device.
2) Should I use a non-metallic junction box or a steel one?
Polycarbonate, like the E987R, is the choice where corrosion is the problem: damp rooms, washdown areas, coastal or chemical exposure, and anywhere you want the insulating properties of a non-metallic enclosure. Steel boxes are the alternative when you need mechanical ruggedness and a metallic raceway ground path, such as the Orbit 4SDB welded steel square deep box or the Orbit D4SB drawn steel 4 inch square.
3) What is a non-metallic alternative to the Carlon E987R junction box?
The Carlon E987R is a molded polycarbonate screw-cover box measuring 6 in. x 6 in. x 4 in. If a non-metallic enclosure in PVC is preferred instead of polycarbonate, the Cantex E983G non-metallic PVC junction box family covers that material. Both are non-metallic; the E987R is polycarbonate with a screw-on cover, while the E983G family is PVC.
4) What should I use instead of the Carlon E987R when a steel box is required?
The E987R is a non-metallic polycarbonate enclosure, so where the job calls for metal, look to a steel box instead. The Orbit 4SDB series is a welded steel square deep box with a 1 in. knockout, and the Orbit D4SB series is a drawn steel 4 in. square junction box 1-1/2 in. deep. Both are steel rather than polycarbonate and are 4 in. square footprints rather than the 6 in. x 6 in. x 4 in. size of the E987R.
5) Does the Carlon E987R come with knockouts already in the box?
The E987R is a molded polycarbonate screw-cover box; its described construction is a sealed enclosure body with a screw-on cover, so conduit or cable entries are made by the installer. If you want a box that ships with a factory entry, the Cantex 5133690 4-1/8 inch junction box is supplied with a 1/2 inch knockout and cover.
6) Is a screw-cover junction box okay for a location that gets inspected or re-entered?
Yes. The cover on the E987R fastens with screws, so it stays closed in normal operation but can be opened for inspection or to pull a new conductor through a splice without disturbing the box body or the conduit entries. That is the main reason crews pick a screw cover over a snap-on or gasketed clamp cover.
7) Can I use the Carlon E987R to replace a PVC junction box on an existing run?
The E987R is a non-metallic enclosure, so it suits the same non-metallic installations a PVC box does, but at 6 x 6 x 4 inches it is physically larger than a typical 4 inch box and will need its own mounting footprint and new entries. If you want a like-for-like non-metallic swap on a smaller opening, look at the Cantex E983G non-metallic PVC junction box family.
8) I only need a small box for a single splice - is the Carlon E987R overkill?
The Carlon E987R gives a 6 in. x 6 in. x 4 in. interior, which is sized for multiple splices, taps and terminations. For a single splice in a tighter space, a smaller box fits better: the Cantex 5133690 is a 4-1/8 in. junction box supplied with a 1/2 in. knockout and a cover, and the Orbit D4SB is a 4 in. square box only 1-1/2 in. deep.
9) Is the Cantex 5133690 a direct replacement for the Carlon E987R?
No. The Cantex 5133690 is a 4-1/8 in. junction box with a 1/2 in. knockout and a cover, while the Carlon E987R is a 6 in. x 6 in. x 4 in. polycarbonate screw-cover box. The footprints differ, so cover openings and mounting layout will not line up if you are replacing one with the other in an existing installation.
10) I need a box with a knockout already provided - does the Carlon E987R have one?
The Carlon E987R is described as a molded polycarbonate screw-cover enclosure for splices and terminations, with the screw-on cover as its defining feature. If a factory knockout is part of your requirement, the Cantex 5133690 4-1/8 in. junction box is supplied with a 1/2 in. knockout and cover, and the Orbit 4SDB welded steel square deep box carries a 1 in. knockout.
11) How many Carlon E987R boxes come in a pack?
The E987R ships as a 10-pack, which is sized for a job with multiple splice points rather than a single replacement. If you are buying for a large rough-in and only need 4 inch square steel boxes, the Orbit D4SB is sold in packs of 100.
12) For a job with many boxes, which option comes in the largest bulk quantity?
The Carlon E987R polycarbonate screw-cover box is supplied as a 10-pack, which suits multi-point installations needing the 6 in. x 6 in. x 4 in. size. If the opening accepts a 4 in. square drawn steel box instead, the Orbit D4SB series 1-1/2 in. deep box is packed 100 to a carton.
