Purpose
Ranging from 2.5 to 30T, the Rigging Projects Internal Lock covers the entire range of yachts, from performance driven race yachts, right through to
the biggest superyachts.
The Rigging Projects Internal Lock is designed to enable the sail to be locked and unlocked without the need for any trip line or external device. The
system allows the user to lock or unlock by simply over hoisting the halyard through the lock.
Use of this product for other than normal sailing vessels applications is not covered by the limited warranty.
Internal Lock key design features:
•No need for internal trip line within the rig.
•A two-pawl system reduces the stress on the body when compared to a single pawl system.
•Coming off lock simply requires a small over hoist on the halyard.
•Cut out within the lock to be able to inspect the mechanism without removal.
AVAILABLE SIZES
The Internal Lock is available in a range of 2.5 to 30T. Internal Locks can be specified with or without an integrated sheave.

Installation
Internal Lock Installation into spar
•Installation of a Rigging Projects Internal Lock should only be carried out by a suitably qualified and experienced personnel. If in any doubt,
contact Rigging Projects.
•Installation should only be carried out using the router jigs supplied by Rigging Projects.
•Tube engineering should be checked prior to locks being fitted to any spar –If in any doubt, contact Rigging Projects first.
1. Working with the spar on the ground, position the router jig in the correct position and secure using the two lock mounting bolts.
2. Once happy with the position of the lock, cut out the slot within the jig plate and tidy up with a drum sander to achieve a neat finish.
3. Angle the top of the lock into the slot in the spar and push through until the lower edge passes through the slot.
4. Tilt the lock back to the upright position and pull towards the front of the rig until it seats in the slot. Fit the two mounting bolts and tighten to
pull the lock into place. These mounting bolts should be fitted with Loctite.

Operations & Procedures
Procedure for Internal Lock
To Lock
1. After connecting the sail to the lock strop, begin hoisting the sail on the halyard.
2. As the bullet reaches towards the entrance of the lock body, reduce the speed at which the line is winched.
3. Keep raising the line until the bullet passes through the snap ring in the lock. For going on lock, there is no limit to the amount the line can be
over hoisted.
4. Once the line has been over hoisted sufficiently, ease down slowly on the halyard until the locking pawls engage. Before removing the hoist line
from the winch, increase the tack load to ensure that the lock is engaged.
5. Line can now be completely removed from the winch.

Operations & Procedures (cont.)
Procedure for Internal Lock (cont.)
To Unlock
1. Before removing any load on the tack, load the hoist line onto a winch.
2. Once the tack is released, slowly wind the hoist line to take up the tension. Only a small over hoist is required to open the pawls.
3. After a small over hoist, the hoist line can be slowly eased down to ensure the lock has been released. If unlocked, drop the sail as normal.
4. If the over hoist on the hoist line is too much, the mechanism will reactivate and lock. A smaller over hoist is required to open the pawls without
reactivation.

Maintenance & Checks
The following maintenance and checks should be carried out on the lock as per the below sheet.
Rigging Projects equipment is designed for minimal maintenance, but some maintenance is required for optimum and safest possible operation and
to comply with the Rigging Projects limited warranty. In general, the most important aspect of maintenance is to keep your equipment clean by
frequently flushing with fresh water. In corrosive atmospheres, stainless parts may show discoloration around holes and screws. This is not serious
and may be removed with a fine abrasive.
IMPORTANT! Exposure to some teak cleaners and other caustic solutions can result in discoloration of part and is not covered under the Rigging
Projects warranty.
