These hydraulic hand operated units are most commonly used for prototyping and small production runs. There are two basic units in the 7006 style, a standard unit which can utilize 3.0 or 4.6 size Tog-L-Loc^® tooling, or a heavy duty unit which can utilize 5.5 Tog-L-Loc^® tooling. Each unit is available in one of two (2) different anvil styles, the style of anvil required depends on the design of part being joined. A hydraulic pump and a spring or air balancer (sold seperately) is required to operate the unit. For increased flexibility, an optional gyro ring can be purchased from BTM which will allow the unit to rotate 360^o on 3 axes.
