Carlon E987NX – Frequently Asked Questions

1) Will the Carlon E987NX cover fit a standard 4x4 square junction box?
The E987NX is a 4 inch by 4 inch square PVC cover, so it lands on standard 4x4 square box geometry. If the box you are covering is a 4-11/16 square (the larger commercial box), this is the wrong size and you need the 4-11/16 cover instead.
2) Does the Carlon 4x4 PVC box cover have any knockouts for a device or fixture?
None. The E987NX is a blank cover with zero knockouts, so it seals the box and nothing passes through it. If you need to mount a receptacle, switch, or a lampholder on the cover, this is not the part; you want a device cover with the matching opening.
3) Can this Carlon PVC junction box cover be used outdoors or in a wet location?
It is built for outdoor use as well as indoor. The cover is PVC with an integrated FIP gasket that seals against the box rim to keep moisture out, and the blank face with no knockouts means there is no opening to leak through. PVC also holds up to UV and chemical exposure, which is why it goes on outdoor lighting and power distribution boxes.
4) Do I need to buy a separate gasket for the Carlon E987NX cover?
No separate gasket to order. The FIP gasket is integrated into the cover, so it ships ready to seal. That is the difference between this and a plain blank cover plate, which needs a gasket bought alongside it to make a weatherproof joint.
5) Is the Carlon square cover PVC or metal, and does that matter for a corrosive environment?
PVC, not steel. That is the reason to pick it in a car wash, a pool room, a food plant washdown area, or anywhere salt air eats galvanized covers: the plastic will not rust and it resists chemical attack. Where the trade-off shows is mechanical abuse, since a steel cover takes an impact better than plastic.
6) What is the Carlon part number for the 4x4 gray PVC blank box cover with gasket?
E987NX is the Carlon catalog number for the 4 inch square gray PVC blank cover with the FIP gasket. That is the number to quote when matching what is already installed on a job or reordering for a facility standard.
7) Can I use this blank PVC cover to close off an abandoned junction box during a remodel?
That is exactly what a blank cover is for. Code requires every junction box to stay covered and accessible, and the E987NX closes a 4x4 square box with no openings once the splices inside are capped. The gasket makes it suitable for a box left in an exterior wall or a damp area.
8) What color is the Carlon 4x4 square box cover, and will it match my existing PVC boxes?
Gray, the same gray PVC used across standard nonmetallic electrical boxes and fittings, so it blends with an existing PVC run rather than standing out. For a property manager standardizing covers across a building, buying one part number keeps every box looking the same.
