PTP 100-A-Constant Spring

Fig. Ptp 100-A
*Drawing shown for down travel

Figure PTP 100-A is a vertical constant suspended from a beam. It can be furnished either with single rod suspension or double rod suspension as shown above. The single rod suspension must be mounted flush to the bottom of the beam where the suspension rod is 1/4 inch thicker than J-Rod. Note that the rod take out (RTO) for the single rod suspension must be adjusted by subtracting 1/4 inch from the values given in the tables below.

ORDERING: Specify figure number, size, type, load, actual travel, total travel and direction of travel. For load and travel not in the tables, please call for dimensions.
