Topaz Lighting 871 – Frequently Asked Questions

1) Can I use a Topaz 1/2 inch watertight connector to bring UF cable into an outdoor junction box?
That's exactly what the Topaz 871 connector is built for. It's a compression-type fitting made for UF (underground feeder) cable, with a rubber grommet that seals around the cable jacket to keep water out of the enclosure. Typical uses are UF terminations at panels, exterior junction boxes, and weatherproof enclosures. The body is zinc for corrosion resistance in wet locations, and it's UL Listed.
2) Will a 1/2 inch UF cable connector fit a standard 1/2 inch knockout?
Yes. The Topaz 871 is a 1/2 inch trade size fitting and lands in a standard 1/2 inch knockout in a box, panel, or enclosure. Trade size here refers to the hub thread, not the cable diameter, so size the fitting to the knockout you're entering and the grommet handles the cable.
3) Is this UF connector the same as a watertight cord grip or a NM cable clamp?
No. The Topaz 871 is specifically a UF cable connector, meaning it's made to terminate flat underground feeder cable and seal it against moisture. A standard NM (Romex) clamp connector is a dry-location fitting with no grommet and no watertight rating, so it should not be substituted where water can reach the entry. If you're feeding a wet-location enclosure with UF, the sealed compression fitting is the right part.
4) Do I need special tools to install the Topaz 871 compression connector?
No special tooling. It's a compression assembly, so you slide the cable through, seat the grommet, and tighten the gland nut down to compress the seal against the jacket. No crimper, no die set. The 871 is 1/2 inch trade size.
5) Is there a 3/4 inch version of this Topaz watertight connector, or a steel one?
Yes on both counts. Topaz makes the watertight connector line in 1/2 inch and 3/4 inch trade sizes, and in zinc or steel bodies. The 871 is the 1/2 inch zinc version. If you're standardizing across a building, pick the body material and trade size that match the knockouts and the environment, then keep to the same family across openings.
6) Is the Topaz 871 UF connector UL Listed for inspection?
It is UL Listed, and it's rated as suitable for watertight applications. That's the documentation an inspector looks for on a wet-location cable entry. Part number is 871, 1/2 inch trade size.
7) Is the zinc body going to hold up in a coastal or continuously damp location?
The 871 uses a corrosion-resistant zinc body, which is what carries it in moisture-prone and outdoor service. For facility buyers standardizing on one fitting across wet-location work, that's the point of the zinc over a plain plated steel fitting. Topaz also offers this connector in a steel body if your spec calls for it.
