Drop the hammer and screwdriver! This compact spring platform tool will get into the tightest spots. Use a standard 3/8 inch square drive ratchet wrench with an extension to reach virtually anywhere.
This super-compact tool was originally designed for spring platforms commonly used with 2 1/2 inch I.D. springs. However, it will also work with most 2 1/4 inch I.D. spring platforms. If the radius doesn't quite match your platforms, a little work with a bench grinder will help.
