CP400™ Silent Cranking Device [Crossbow Crank]

What is CenterPoint Archery CP400™ Silent Cranking Device [Crossbow Crank]?

The CenterPoint Archery CP400™ Silent Cranking Device is a purpose-built cocking aid for the CP400 crossbow. It attaches to the rifle-style rail and lets the archer draw the string with a hand-crank instead of manual pull, delivering a smooth, quiet cocking motion that reduces physical strain. The crank’s low-profile housing integrates seamlessly with the CP400’s stock, ensuring the balance point remains unchanged. Its sealed bearings protect against dust and moisture, extending service life even in harsh field conditions.

Who is CenterPoint Archery CP400™ Silent Cranking Device for?

This crank is ideal for hunters who need a stealthy draw, competitive shooters looking for consistent cocking speed, and archers with limited upper-body strength or mobility concerns. Because it mounts on both sides, it serves left-handed users as well as right-handed ones. The device also benefits bowhunters who operate in cold weather, where manual draws can become stiff. Its ergonomic crank handle provides a comfortable grip, reducing hand fatigue during extended sessions.

How does CenterPoint Archery CP400™ Silent Cranking Device compare?

Compared with generic hand-crank accessories, the CP400 device offers a tighter fit, higher mechanical advantage and a quieter gear train, but it only works with the CP400, whereas generic cranks can attach to many crossbow platforms. They may lack the sealed bearings and ambidextrous mounting that make the CP400 crank especially reliable in field conditions. When measured on a decibel meter, the crank registers less than 55 dB, well below the threshold that typically spooks game. Users report a 30-second reduction in overall reload time compared with traditional lever pulls.
