The hydraulic cylinders body has two mounting holes which enables fixing to machinery such as, fixtures, clamping jigs, spreader plates, etc., the plungers load contact area is also grooved to increase its horizontal grip.
The jack should only be operated between parallel surfaces, if this is not the case then use a steel tapered shim which must cover the full plunger area or install and level a steel plate bedded on a high strength mortar or grout.
