Rigging (continued)
Adjusting the Angle Between Enclosures (Splay)
The illustration below shows the rear receiver block of two enclosures joined by the upper enclosure’s rear link (enclosures and ball lock pin
lanyards omitted for clarity). Note the link is marked in two locations when extended. The unlabelled white line nearest the end of the link
is the normalized (or 0°) hole position marker. The white line above it labeled with +3 is the +3° hole position marker. When using the nor-
malized hole position in the link, the splay between the enclosures is as marked on the receiver block. When using the +3 (+3°) hole position
in the link, add 3° to the receiver block position the link is pinned into.
The left-side illustration shows the use of the normalized (0°) link hole position. The splay angle between the upper enclosure and the one
above it (not shown) is 0° because the link is pinned through its normalized hole location and the is pinned into the block at the 0° position.
The splay angle between the two receiver blocks shown is 2°; again, the link utilizes the normalized hole position and the is pinned into the
block at the 2° location.
The right-side illustration shows the use of the +3 (+3°) link hole position. The splay angle between the upper enclosure and the one above
it (not shown) is 3° because the link is pinned through its +3 hole location and the is pinned into the block at the 0° position. The splay angle
between the two receiver blocks shown is 5°; again, the link utilizes the +3 hole position and the is pinned into the block at the 2° location.
Upper enclosure
pinned for 0° splay.
Pin is at 0° location,
link uses normalized
hole position.
Lower Enclosure
pinned for 2° splay.
Pin is at 2° location,
link uses normalized
hole position.
Upper enclosure
pinned for 3° splay.
Pin is at 0° location,
link uses +3° hole
position.
Lower Enclosure
pinned for 5° splay.
Pin is at 2° location,
link uses +3° hole
position.
Link marking detail-
line closest to the
link’s end is the nor-
malized (0°) hole
location and the line
labeled +3 is the +3°
hole location.
