Greenlee 51840120 – Frequently Asked Questions

1) What size drill bit do I need for the Greenlee 51840120 conical anchor kit?
Drill the pilot hole with a 1/4 inch bit. The conical plastic anchor is sized to that hole, so going larger leaves the anchor loose in drywall and going smaller means it won't seat flush.
2) Does the Greenlee 51840120 anchor kit come with screws, or do I buy those separately?
Screws are included. The kit pairs its conical plastic anchors with #10 x 1.000 inch Type C screws, so nothing else is needed to set a mounting point once the 1/4 inch hole is drilled.
3) Will a conical plastic anchor hold a light fixture on drywall, or do I need a toggle?
For boxes, devices, and light fixtures on drywall the 51840120 conical anchor works as intended: the tapered plastic body expands against the board as the #10 x 1 inch Type C screw drives in. It's a drywall-type anchor, so it is suited to the residential and light commercial mounting the kit is built for rather than heavy structural loads.
4) How do I order the right Greenlee conical anchor kit, and what is the part number?
Order it by Greenlee part number 51840120. It's a single configuration, so there are no finish, size, or screw-length options to specify: one kit, 1/4 inch bit size, #10 x 1 inch Type C screws.
5) What does the #10 and #12 wire size rating on the Greenlee 51840120 kit mean?
The kit is rated for #10 and #12 wire, the two gauges that cover most 20 and 30 amp residential and light commercial branch circuits. That's the wiring context Greenlee sizes the kit for, not a limit on what the anchor itself can be screwed into.
6) Are the Greenlee 51840120 anchors metal or plastic, and will they corrode in a damp wall?
The anchor bodies are plastic, which is why they don't corrode the way a metal anchor can in a damp or humid wall cavity. The mating fastener is a #10 x 1 inch Type C screw.
7) How big is the Greenlee 51840120 anchor kit box, and will it fit in a tool bag pouch?
The kit measures 7.500 x 3.300 x 1.600 inches, about 39.6 cubic inches of volume, so it drops into a standard van bin or a tool bag pouch without taking a shelf.
