Someone recently asked where to get replacement level vials. I've lost the
original posting, but thought I would throw out a few possibilities:

Empire Level Mfg. Corp.
P.O Box 26187
Milwaukee, WI 53226-0187
414-475-9270 EXT 334

Johnson Level & Tool
1-800-776-3614

John J. Chaloux & Co. INC
518-273-6564

Most of the new spirit level vials are made of acrylic plastic. Don't know
if any of these companies still make glass vials.

Good Luck
