Spencer 3/8? Wide Combination Logging Tape Refills are designed with Decimal (10ths) on front and Diameter (10ths) on back. The blades are nylon coated for added durability.
Spencer logger tapes and diameter tapes are often broken in the field due to twisting, kinking or cutting. Replacing them is a fairly simple process and can be done in the field with a small screwdriver. Refills come bare (without nails or an attachment screw), so be sure to order those parts separately if needed
