The STH series style H, are side mounting frame take-up units designed to incorporate the ST series take-up units (see pages G-72 to G-74), as indicated in the accompanying charts.
They are used where shaft adjustment and/or belt tightening is required in conveyor applications. They are manufactured from heavy gauge structural steel members and equipped with heavy duty Acme
(square) threads for positive action.
Adjustment is made by turning the square head with an open end wrench.
