Fitting of Orbit Blocks™
with Dyneema
®
Links
• For best results, the Dyneema
®
Link must be attached
to a mounting point with a smooth, well rounded profile.
• Avoid attaching directly to fittings with sharp edges or
rough surfaces that may damage the Dyneema
®
Link
through abrasion or point loading. For this situation use
a shackle with a smooth surface between the Link and
the fitting.
1.1
(Diagram 1.1)
Attachment at 90° (transverse)
1.1.1
Use a shackle key or small
screwdriver to release one side of
the Retainer Clip. Use a finger to
hold the other side of the Retainer
Clip in place.
1.1.2
Remove the free end of the
Dyneema
®
Link from its recess in
the head of the block.
1.1.3
Pass the Link through the mounting point.
1.1.4
Press the end of the Link over
the Retainer Clip and firmly back
into its recess in the block. A
little tension on the Link may
help to settle it into position.
1.1.5
Snap the Retainer Clip back
into place over the Link. An
audible “click” confirms secure
attachment.
1.2
(Diagram 1.2)
Attachment at 0° (in-line)
1.2.1
Use a shackle key or small screwdriver to release one
side of the Retainer Clip.
1.2.2
Remove the end of the Dyneema
®
Link from its recess
in the head of the block.
1.2.3
(Diagram 1.2.3)
Twist the Link anti-
clockwise 360° (i.e.
first twist 180° to form
a figure-8 shape, then
twist again).
1.2.4
Pass the Link through
the mounting point,
taking care to keep it twisted as described above.
1.2.5
Press the end of the twisted Link over the Retainer
Clip and firmly back into its recess in the block. A little
tension on the Link may help to settle it into position.
1.2.6
Snap the Retainer Clip back into place over the Link. An
audible “click” confirms secure attachment.
1.2.7
(Diagram 1.2.7)
Rotate the block clockwise back to 0° and pull slightly to
align and tension the link symmetrically.
1.3
Attachment at 0° or 90° to a Pin, Shackle, Saddle,
or Control line, etc.
1.3.1
Use a shackle key or small screwdriver to release one
side of the Retainer Clip.
1.3.2
Remove the end of the Dyneema
®
Link from its recess
in the head of the block.
1.3.3
Twist the Link anti-clockwise 180° to form a figure-8 shape.
1.3.4
Press the end of the twisted Link firmly back into its
recess in the block. A little tension on the Link may help
to settle it into position.
1.3.5
Snap the Retainer Clip back
into place over the Link. An
audible “click” confirms
secure attachment.
1.3.6
(Diagram 1.3.6)
Pass a shackle, saddle, pin,
or rope end through the Link
(which now has a single
crossover) at 0° or 90° to
the block, depending on the
desired alignment.
1.4
Other Attachment
1.4.1
Snap shackles (fixed or swivel) can be fitted to Orbit
Blocks™ using the methods described above for 0° or
90° attachment.
1.4.2
(Diagram 1.4.2)
Custom lashings, strops or
Links can be made from
Dyneema
®
rope of the same
diameter as the supplied link.
Note; where required to fit
around an object wider than
the head of the block (eg a
boom) the ends of the custom
Link must cross each other
prior to being fitted into the
recesses in the head of the
block. The Maximum Working
Load and Breaking Load of the
assembly (Block + Link) is
limited by the strength of the
rope and the joining method.
Knots, splices, stitching, etc. will generally have a lower
Breaking Load than the rope itself.

Fitting of Sheets/Lines to Beckets
IMPORTANT: Ronstan Orbit Blocks™ have several
unique becket arrangements. To avoid improper
loading or failure of the becket, use only the
correct method of line attachment for each type as
described below.
