the spear’s usefulness by providing an extended catching range beyond the

Grapple is used in place of the standard one-piece Grapple on the 9 5/8” Spears
to convert them to spears capable of engaging up to 20”

grapple body, eight grapple segments, two retainer rings, six retainer ring
screws, six retainer ring spacers, and sixteen grapple segment
screws.
Pack-off

tubing and casing. Circulation through the fish is enabled by attaching the
Spear Pack-off Assembly to the bottom of the spear with a sub type
nut.

stop ring can be added to increase shoulder diameter. All stop rings are
furnished with left-hand threads.
