Greenlee 50026690 1/4-20 Screw Anchor Expander, Hardened Alloy Steel

The Greenlee 50026690 is a 1/4-20 screw anchor expander designed for use with caulking anchors, giving electrical and mechanical contractors a reliable way to set anchors securely into masonry and concrete. Machined from hardened alloy steel, this expander is built to withstand the repeated striking and pressure required to properly seat caulking-style anchors, making it a durable addition to any installer's toolkit. It is intended for use with anchor number 84299, and its 1/4-20 thread size and 20-thread expansive belt size match that anchor specification precisely for a proper, code-compliant fit.

At 5.050 IN long, 2.550 IN wide, and 1.850 IN high, the expander is compact enough for easy one-hand handling on ladders, in crawlspaces, and other tight jobsite conditions, while still delivering the leverage and durability needed to expand a caulking anchor sleeve to its full seated diameter.

Greenlee 50026712 – Frequently Asked Questions

1) What size screw anchor expanders does Greenlee offer, and which one do I need?
Greenlee's screw anchor expander comes in two expansive belt sizes: 1/4-20 (part 50026690) and 3/8-16 (part 50026712). Pick the one that matches the thread size of the caulking anchor you are setting, not the size of the bolt hole. The 1/4-20 version is made to set anchor number 84299.
2) Will this Greenlee expander work with drop-in or wedge anchors, or only caulking anchors?
Caulking anchors only. The Greenlee screw anchor expander is a setting tool for caulking-style lead anchors, where the expander drives the sleeve out against the hole wall. Drop-in anchors use their own matched setting punch, and wedge anchors need no setting tool at all, just torque on the nut. Using this on the wrong anchor type won't seat it.
3) Is the Greenlee anchor expander tough enough to be struck repeatedly with a hammer?
It is machined from hardened alloy steel specifically for the repeated striking and pressure needed to seat a caulking anchor. That is the reason this is a dedicated tool rather than a bolt and washer improvised on site, soft steel mushrooms and stops expanding the sleeve fully.
4) Does the Greenlee 50026690 come with anchors, or do I order those separately?
The expander ships 1/Box as a setting tool only. Caulking anchors are a separate order, and for the 1/4-20 expander you want anchor number 84299 to get the correct expander-to-anchor fit.
5) How big is the Greenlee screw anchor expander, and can I use it one-handed overhead?
The 1/4-20 expander measures 5.050 inches long, 2.550 inches wide and 1.850 inches high, so it handles one-handed on a ladder or in a crawlspace while still giving enough body to drive the anchor sleeve out.
6) What kind of work is this anchor expander actually used for on an electrical job?
It sets caulking anchors into concrete and masonry so you can hang conduit supports, electrical boxes, and brackets. Typical use is renovation and new commercial construction anchoring, and it is small enough to live permanently in a service truck or install kit.
