Span any distance from inches to yards with the Lightning Clamp. It’s like a pipe clamp that uses threaded rod instead of pipe, but it offers several advantages. It’s lighter; the threaded rod gives you mechanical advantage to apply high pressures; and the large faceplates spread the clamping pressure over a greater area.
The lightning clamp consists of a fixed plate, a sliding faceplate, and one or more sections of threaded rod joined by a coupler. You can also substitute the fixed plate with the included deck grip.
You slide the sliding plate up to the work, lock the lever, and turn the knurled handle on the threaded rod to tighten the clamp. To release the clamp, simply flip the locking lever. You can also convert the clamp to a spreader by reversing the position of the fixed and sliding plates.
Built to stand up to professional use, the lightweight clamp is manufactured from heavy-duty mild steel, and it breaks down for easy transport and storage. It works with any 12mm zinc-plated SA5 or other smoothed-surface threaded rod, but it’s not compatible with hot-dipped galvanized rod because the coating increases the diameter of the rod and makes the threads too rough.
Looks like you can purchase a Lightning Clamp for $20 at Amazon, but you’ll have to provide your own 12mm threaded rod.
