K7LI Universal Key Base and other Offerings

---

The K7LI Universal Straight Key Base is designed to accept many popular vintage and modern keys. We don't guarantee it will work with every straight key out there, but it has been tested with many. The 4"x 6", 3/16-inch-thick steel base has a variety of threaded 6-32 mounting holes + 2 non-thread 5/32" holes.  Please see the list below for information on compatible keys and hole spacing.  The steel plate is attached to non-slip rubber feet and weighs 1.3 pounds, so it provides a sound anchor for sending CW. The black powder coated steel plate is covered with a textured black 1/8" thick plastic cover slightly bigger than the key base. (Note: first production run was painted black).  Hardwood covers are also available. The cover ships with no holes but the bottom of the cover has guide holes that extend about halfway through the cover. You pick the holes for your key and finish drilling or knocking out the hole in the cover which then perfectly aligns with the steel base.  It was designed and manufactured in Utah with US sourced steel.  

The base ships with 6-32 machine screws (2 round head ½” brass screws with washers, 2 flat head ½” screws and two round head 7/8” screws with nuts) with will work on most key.  Scroll down to see the instruction sheet for adapting the top plate.

If we have missed a common hole spacing or key, let me know and we will look at incorporating it in the next production run.  Scroll down to see the instruction sheet for adapting the top plate. 

We also offer a limited selection of vintage restored keys and bugs.  Every key we restore is as close to the original as we can get it. We gently clean and polish each key as best we can. These are vintage keys and most show wear and tear. If any parts have been replaced with modern equivalents, we try to mention that in the product description.  Most of our keys are sold on our base.  Our Inventory is constantly changing, and we frequently only have one of a particular key.  What you see in the product description is what you get.
