Dynello Accu Winder is an effective tool that transforms any cordless drill into a strap winder. The product is perfect for those who have their own drill and periodically use many lashing straps for load securing.

Install the Dynello Accu Winder easily and quickly in the drill with its Ø10mm shaft. The strap winder tool can be used to wind ratchet straps, roundslings, slings, tie downs wet or dry, utilizing the powerful torque of the drill.

Adjust the torque with the cordless drill's torque control to give the strap the right 'tightness'. You can conveniently squeeze the moisture out of the ratchet strap during rewinding so it dries up faster.

The strap winder rolls-up a strap in less than 7 seconds! You will without a doubt save many hours on strap winding with a Dynello Accu Winder. The investment is quickly earned in saved time!

Investing in a Dynello Accu Winder is not only good for the economy, but also for your work environment. Avoid the repeated work with manual strap winding by hand.
