Viking 4in. in. Digital Clock Wire Guard - CL-WGD4

Viking Electronics CL-WGD4 Digital Clock Wire Guard

Overview

The Viking Electronics CL-WGD4 is a protective wire guard designed for Viking's 4-inch CL-Series digital clocks, including the Viking CL-D4. Wire guards serve a straightforward purpose in commercial and institutional installations: they protect clock faces from incidental contact, deliberate tampering, and physical damage in high-traffic or rough-use environments — gyms, warehouses, corridors, cafeterias, and manufacturing floors where a bare clock face is an invitation for damage.

The CL-WGD4 (sometimes searched as CL WGD4) pairs directly with the 4-inch digital clock variant in the CL Series wireless clock line. The underlying CL-D4 clock uses 915–928 MHz frequency-hopping technology to receive and re-transmit a sync signal every minute — the wire guard mounts over it without interfering with the internal antenna or RF operation. If you are building out a synchronized clock system for a facility-wide timekeeping deployment, pairing each exposed clock with the appropriate wire guard is standard practice in environments where clocks are mounted within reach.

Compatibility

The CL-WGD4 is designed specifically for the 4-inch digit Viking CL-Series digital clock (CL-D4). It is not cross-compatible with the 2.5-inch digit variant or the 16-inch analog CL-A16 — those require their own guard accessories. Confirm your clock model before ordering. The CL Series accessories line includes guards and hardware matched to each clock size in the family.

Installation Notes

Wire guards in this class typically mount to the same wall or ceiling surface as the clock, using the clock's existing mounting footprint or a bracketed overlay. The host CL-D4 clock operates on 90–230V AC (via included power adapter) and measures 11 inches wide by 8 inches tall by 1.7 inches deep — size the guard clearance accordingly. Because the CL-D4 uses an internal antenna for its 915–928 MHz RF sync link, ensure the wire guard material does not create a Faraday cage effect that would attenuate the signal; Viking's own accessory guard is designed to avoid this issue by construction.

Frequently Asked Questions

Q: Which Viking clock does the CL-WGD4 wire guard fit?

A: The CL-WGD4 is designed for the Viking CL-D4, the 4-inch digit digital clock in the CL Series. It is not compatible with the 2.5-inch digit CL-Series clock or the CL-A16 analog clock — each size requires its own matching guard.

Q: Will the wire guard interfere with the CL-D4's wireless sync signal?

A: The CL-D4 uses 915–928 MHz frequency-hopping RF to receive and re-transmit its clock sync signal every minute. Viking's purpose-built CL-WGD4 guard is designed for use with this clock and should not block or degrade that RF link. A generic third-party metal cage, by contrast, could attenuate the signal.

Q: What environments is the CL-WGD4 suitable for?

A: Wire guards are standard in high-traffic, rough-use, or tamper-prone areas: gymnasiums, warehouses, school corridors, manufacturing floors, cafeterias, and similar institutional or industrial spaces. The guard deters physical contact and protects the clock face and housing.

Q: Does the CL-WGD4 come with mounting hardware?

A: Package contents for the CL-WGD4 are not detailed in available product documentation. Contact the seller for exact box contents before installation planning.

Ted Perry

The CL-WGD4 is the wire guard accessory for Viking's 4-inch CL-Series digital clocks. The detail that matters most in specifying this part is clock-size match: the CL-D4 clock housing runs 11 inches wide by 8 inches tall, and the CL-WGD4 is dimensioned for that footprint — ordering the wrong guard for a 2.5-inch or analog clock in the same CL family is the most common field mistake I see on these installations.

Technical Highlights:

• RF Transparency: The CL-D4 syncs over 915–928 MHz frequency-hopping every 60 seconds; the CL-WGD4 guard is designed not to attenuate that link — critical when the clock also functions as a repeater, re-transmitting to downstream clocks in a daisy-chain layout.
• Size-Specific Fit: Matched to the CL-D4's 11
