Product Description
Used to mount either one or two Fiber Optic
Quadrant Blocks (15316)

Must be secured to pulling irons found in the

Lightweight, all aluminum construction
provides a maximum load strength of 3000 lbs.
Made of two U shaped members, each of
which has a separate swiveling safety hook
on one end. Both members are joined by a
special bushing. An L shaped 1 5/16" locking
pin fits through this bushing to support the

To change, add or remove a block, you just
remove the locking pin; the shackle stays
together. A knurled knob, that is tethered to
the shackle, allows you to open it on one side
Two self storing spacers come with each
shackle to securely center one block. When
