The purpose of the KF816.3 is to be a base for different training machines of the KF816 line. Among them are a bench press, bench for a reverse crunch, and a hyperextension. 

The Triple base has excellent resistance to any weather condition and rapid temperature variations. The special coating protects the equipment, making it fearless of corrosion, mechanical damage, fading in the sun, and abrasion. Zinc covering of the KF816.3 makes the base even stronger.
