STI’s super tough wire guards protect clocks, bells and similar devices against abuse and other damage
These super tough wire guards are designed to protect clocks, bells and similar instruments.
Three sizes are available to cover a wide range of units. Each is constructed of 9-gauge steel wire with corrosion resistant polyester coating (or stainless stee). Their octagon, spider web like shape also helps them take tough knocks in stride.
As all STI protective wire guards, these Stoppers are backed by a lifetime guarantee against breakage in normal use. Also, because they are white in color, users report that their clock numbers are easier to see than with darker competitive guards. Installation is easy and tamper resistant hardware (screws and bits) are available.

- Constructed of coated steel wire or stainless steel.
- Fast and easy installation.
