The 418 Trigger cleat allows easy
release of highly-loaded lines with
complete control. Pulling line down
on the trigger mechanism opens
cleat. Line never comes off cleat.
The trigger serves as a snubbing
surface to control release.

Installing 418 Trigger Cleat
Placement
The angle of line from cleat to operator is important for efficient
release. For best operation, mount cleat at waist or chest height
in your normal operating position. If possible, mount cleat on
edge of deck, cockpit, or cabin.

If line angle is too low, or if cleat cannot be mounted near an edge, mount
cleat on pad or bracket inclined 25°. Install bullseye fairlead or turning

Adjusting Cleat to Fit Line Size
The Trigger cleat will accept most lines up to 12 mm (
To adjust cleat to fit larger size line,
loosen screws and lift cam cleat and
its platform slightly from base. Slide
base toward you, against spring
tension. Press cleat and platform
down and hold in place until screws
are tight.
Tip: Mount screws through cleat and deck with nuts loosely threaded.
Screws should be ready to tighten before adjusting for larger line.
Cam base and cam platform have ridges and interlocking grooves
to help hold them in place until screws are tight.

Check for Proper Adjustment
With lever fully depressed, cam gap should be
slightly larger than line size. If gap is too small,
shift base to position for larger line size.
With line loaded in cams, lever should not
contact top of lever cavity. This will prevent
cams from closing tightly against line. If rope
slips when loaded, shift base to position for
smaller rope size.

How Trigger Cleat Works
Pull line tail downward as in position B. The release lever opens cams so
line may be eased. By holding a downward angle, lever acts as a snubbing
surface for better control of heavily loaded lines.
Raise line tail (position C), or simply release line (position A).
Spring-loaded cams close to cleat line again.
Fairings around release lever allow cleating when tail leaves cleat at up
to 45° to either side of cleat axis. Line stays between cams at all times.

If parts are under load during long passages, it is important
to inspect them carefully while in use. Failure to inspect and
correct block and loop or lashing can result in block breaking
under load causing an accident, or damage to your vessel.
