Antal DV Jammer For 10mm Lines Side Mounting
The Antal DV Jammer For 10mm Lines Side Mounting is a specialist line-holding device designed to deliver maximum grip, durability, and safety in high-load sailing applications. Using Antal’s patented Double V-Grip system, this jammer distributes pressure evenly around the line to reduce slippage and minimise cover wear—making it ideal for modern rope technologies such as Dyneema® cores with high-tech covers as well as traditional polyester lines.
Key Features
-
Side-mounting design – Perfect for bulkhead or mast installation where a flush deck-mounted jammer is impractical.
-
Double V-Grip mechanism – Two opposing V-shaped wedges apply a four-sided grip, automatically tightening as load increases. This ensures reliable holding power with less localised abrasion compared to conventional jammers.
-
Safe Working Load (SWL) – Rated to 2,000 kg, making it suitable for demanding halyard and sheet applications.
-
Line compatibility – Optimised for 10 mm lines, striking the right balance between grip security and line longevity.
-
Corrosion-resistant build – Manufactured with marine-grade alloys and stainless steel components for long service life in harsh offshore conditions.
-
Smooth operation – A ratchet-assisted slider makes engaging and releasing the jammer straightforward, even under heavy load (release must always be managed with a winch).
Applications
The Antal DV Side-Mount Jammer for 10 mm lines is particularly suited to halyards, reefing lines, and high-load control systems on performance cruisers and racing yachts. Its side-mount format makes it a versatile solution for mast-mounted halyard jammers, keeping the deck clear and optimising line lead.
