Hi Harvey, I can't give you an expact P/N since it's been quite awhile since I bought and installed the hasps. Hasps and pad locks on sail lockers (and companionways) are a necessity if you are leaving the boat in a marina, or parked on a trailer somewhere. I bought the smallest ones I could find - as well as three identically keyed Abus brass locks. That simplifies life - only one key needed to open all three locks.
From looking at my WEST catalog (1999 Edition - page 196) I think what I have is "L" - "Stainless Hasps", and of the three shown, mine is probably the smallest one - Model No. 279026.
When I installed them, I first put 1" closed cell foam seals on the insde of the sail locker lid, so that when the lid is closed, the foam strips seal the edge of the sail locker. Keeps out water as well as little crawly things looking for dark living places. Then I put the eye in place on the lid - drilling holes and using flat headed S/S bolts and elastic stop nuts on the inside. Then I located the folding part of the hasp on the inboard side of the cockpit, so that when the hasp was open that part would hang down and be out of the way. I located my holes so that it needed a slight force fit to get the hasp in place over the "U". That way, when sailing I have the lockers closed - no locks in place -and they won't open inadvertantly. However, exert a bit of force and they are open and the contents of the sail locker become instantly accessible.
