In 2020, Alphalock‘s versatile Modular series , an all new automatic (no tripline) halyard lock based on the original Alphalocks, was introduced. The new concept combined in one product, both the block locks and in-mast locks in the original series.

Version 2.0 is a refinement of that series. Lockplates are Stainless Steel and the Flipper and Bullet are Titanium. Version 2.0 locks are lightweight due to close attention to weight reduction. Because it’s more compatible with carbon masts, Stainless Steel replaces aluminum in the InMast Mastplates.

The new Alphalock Modular Series follows Alphalock’s relentless quest for simplicity with no compromise in strength or function. “Utter simplicity is the Holy Grail of engineering,” says Eric Hall , Alphalock founder and president. “I have been involved with automatic locks since 2007. Each year I thought the locks couldn’t get simpler, but they always did. The new Alphalock Modular Series is the simplest yet. Its reliability and ease of service will be tough to beat.”

Alphalock Modular locks are even simpler: one moving part and a modular system where one lock works as Block Lock or In-Mast Lock, using one common locking bullet. Meanwhile, the locks will have the same strength, function, reliability and ease of servicing as the original Alphalocks. Alphalock Modular locks are the only automatic locks sized to accept full size halyards with or without locking bullets.
