My MIL has had this thing for years and no one in the family can figure out what it is. Any ideas?

If you’ve ever opened an old beekeeping box of tools, you might stumble on a strange wooden, clamp-like device with a handle and a springy metal latch. That tool is known as Parker’s Foundation Fastener, a handy piece of beekeeping history from the late 1800s.
What is it called?
The name most commonly used for this tool is Parker’s Foundation Fastener. Beekeepers also describe it by what it does: a foundation fastener—a device used to secure wax foundation into a wooden hive frame.

When did it appear?
This style of tool dates to the 1800s (19th century), when frame hives became more standardized and beekeepers started using wax “foundation” sheets to guide bees into building straight, uniform honeycomb.
What was it used for?
Its job was simple but important: to attach wax foundation securely into a wooden frame so it wouldn’t slip, bow, or fall during handling.
Here’s what it helped beekeepers do:
- Hold the frame steady while working
- Press or clamp the foundation into place (often into a groove or against a retaining strip)
- Speed up frame preparation so a beekeeper could build more frames faster
- Improve the chance of straight, even comb, which makes inspections and honey harvesting easier
In practical terms, a beekeeper would position the frame and foundation, then use the tool’s clamp action to tighten and fasten the foundation so it stayed put once the hive warmed up and the bees began drawing comb.

Why this tool mattered in the 1800s
Before modern staples, rollers, and mass-produced frame parts, beekeepers needed reliable ways to secure foundation. A tool like this made the work:
- Faster
- More consistent
- Less likely to end with crooked comb (a major headache in hive management)
How to recognize one
From the photos, the classic clues are:
- A wooden handled clamp
- A flat pressing surface (the “jaw”)
- A springy metal latch that keeps tension while fastening
Bottom line
Parker’s Foundation Fastener is an 1800s beekeeping tool designed to secure wax foundation into hive frames, helping beekeepers build straighter comb and prep frames more efficiently. Today, it’s both a functional curiosity and a collectible reminder of how hands-on early beekeeping really was.
