S.L. Waber 952M
S.L. Waber 952M
The S.L. Waber 952M is a three-outlet relocatable power tap manufactured by S.L. Waber and distributed as part of the Herman Miller Energy Distribution System for Panel System Type I office furniture installations. The documented example carries Herman Miller model designations EK410 and PK410 and was intended for use with AO and PG series panel systems.
Overview
The S.L. Waber 952M is a commercial-grade relocatable power tap designed for office furniture power distribution systems. Unlike consumer surge suppressors, the unit provides straightforward power distribution without surge suppression circuitry. The documented example was integrated into Herman Miller's Energy Distribution System and features a heavy-duty metal enclosure, three grounded NEMA 5-15R receptacles, and a long power cord intended for workstation and cubicle environments.
Documented Example
- OldSurge ID: OS-XXXX
- Manufacturer: S.L. Waber
- Integrated System: Herman Miller Energy Distribution System
- Model: 952M
- Part Number: XUL603-038A
- Herman Miller Model: EK410 / PK410
- Serial Number: Not Observed
- Manufacturing Date: Unknown
Weight
The documented S.L. Waber 952M weighs approximately 1.96 pounds (0.89 kilograms). The relatively high weight reflects its steel enclosure construction, integrated 15-amp circuit breaker, and heavy-duty approximately nine-foot power cord.
Compared with typical consumer-grade power strips, the 952M exhibits significantly more substantial construction consistent with commercial office furniture power-distribution applications.

Physical Characteristics
The documented example consists of a rectangular gray-painted metal enclosure fitted with three black grounded receptacles mounted on the upper surface. A Herman Miller identification label on the side identifies the unit as part of the Energy Distribution System for Panel System Type I installations and specifies compatibility with AO and PG series panels.
A separate manufacturer label identifies the unit as an S.L. Waber Model 952M Multiple Outlet Strip, part number XUL603-038A. The label states a 15-ampere, 120-volt, 60-hertz rating and notes assembly in Mexico.
A 15-amp manually resettable circuit breaker is installed at the power-cord entry point. The breaker protects the power tap from overload conditions while maintaining a simple, non-surge-suppressing design.
The manufacturer label identifies the unit as an S.L. Waber Model 952M Multiple Outlet Strip, part number XUL603-038A. The unit is rated for 15 amperes at 120 volts AC, 60 hertz continuous duty and was assembled in Mexico. The label also identifies S.L. Waber, Inc., Mount Laurel, New Jersey, as the manufacturer.
The Herman Miller identification label specifies compatibility with AO and PG series panel systems. The AO designation likely refers to Herman Miller's Action Office product line. The meaning of the PG designation has not yet been confirmed.
The underside of the enclosure incorporates several formed mounting features that appear intended to interface with Herman Miller office panel-system hardware. These structures indicate that the unit was designed as an integrated component of a workstation power-distribution system rather than as a free-standing consumer power strip.
The documented example utilizes a heavy-duty SJT 16/3 power cord approximately nine feet in length. The cord terminates in a molded NEMA 5-15P grounding attachment plug. The relatively long cord length suggests installation flexibility within modular office furniture systems and workstation environments.

Condition Upon Acquisition
The documented example was acquired in complete and functional condition. Moderate dust accumulation was present on the enclosure, receptacles, and power cord, consistent with prolonged use in a commercial office environment. Minor cosmetic wear and scratches were observed, but no major damage or missing components were noted.
Teardown
Internal examination has not yet been performed.
Historical References
The documented example illustrates the use of OEM power-distribution equipment within modular office furniture systems. Herman Miller marketed the unit as part of its Energy Distribution System, while the manufacturer label identifies S.L. Waber as the actual producer.
Notes
- Herman Miller model designation: EK410 / PK410.
- Intended for use with AO and PG series panel systems.
- S.L. Waber later became associated with Tripp Lite branding under the "Waber by Tripp Lite" name.
- The documented example is classified as a relocatable power tap rather than a surge suppressor.
