Semco rotator accessories save time and money when you install your sign and they help protect the rotator too. Some of these accessories are required for safe installations.
The most common accessories include steel louver covers, companion matching plates sized to your sign pole diameter, and split- plate roller assemblies built to match the sign pole diameter.
Louver covers keep out water and allow for ventilation to keep the motor from overheating. These covers are easily removed for routine maintenance.
Companion matching plates fit the turntable plate of the rotator. These typically include four threaded studs welded to the plates to fit into the through holes of the rotator’s turntable and base plates. Depending on your installation you will use one of two of these plates.
Split-plate rollers mount at the base of Figure 1 rotators to support the lower part of the sign when wind pushes against the sign. These only contact the sign pole when pushed by the wind. These are typically used on the larger outdoor signs.
