Rice Lake RLSP4 Aluminum, Single Point Load Cell

As of: Wednesday, September 9, 2026

Standard Features

This is a low-profile, off-center-loading single point load cell designed for retail, postal and platform-scale applications. It's constructed from aluminum, moment-compensated for optimal accuracy and protected by a quality gauge coating compound that provides a barrier against high-humidity environments. The RLSP4 is available in capacities ranging from 7 to 100 kilograms and comes standard with 10 feet of cable.
