Allen Pro-Ratchet 40

The Allen Pro-Ratchet 40 has been developed for sailors who want maximum grip, smooth handling and complete control when trimming under load. Featuring Allen's first 40 mm aluminium sheave, this high-performance ratchet block delivers outstanding holding power while remaining lightweight and compact, making it ideal for modern dinghies, skiffs and sportsboats. 

Designed to reduce the effort required to hold loaded sheets, the aluminium sheave provides significantly more grip than traditional composite ratchet blocks. Whether you're trimming a spinnaker in a gust or easing a jib through a manoeuvre, the Pro-Ratchet 40 helps maintain precise sail control with less strain on your hands.

A built-in 360° swivel allows the block to align naturally with the load, while the ergonomic switchable ratchet mechanism can be turned on or off without tools and even while wearing gloves. This gives you complete control over line feel as conditions change throughout the race.

Despite weighing just 53.2 g, the Pro-Ratchet 40 offers an impressive 180 kg working load and 600 kg breaking load, making it suitable for demanding racing applications. Compatible with ropes up to 6 mm, it performs particularly well with tapered mainsheets and spinnaker sheets on performance dinghies.
