The Katrol S is a mini pulley that has been developed with lightness and efficiency in mind.

This mini pulley has high strength side plates made of 7075 Aluminum. It also features a needle bearing that will allow this pulley to be loaded up and still provide a smooth operation. On top of it uniqueness we believe in the right to repair and for that reason it comes with a bolted assembly so you can take it apart and maintain it.

The bolt itself is made of high strength steel and can also be maintained with a rust inhibitor. Keep in mind that there is a special procedure for putting it all back together again. Loctite or similar is required to secure the bolt inside the shaft.

Most pulleys designs are built for minding a Prusik or not. This unique and typical Eyolf product has both. We have thought of a new way to mind your Prusik, while in other operations it isn’t in the way. Why no one else has thought of this we wonder that too. Simply said it works so you can stick to one style pulley and do what you need to do.

This small pulleys also sits perfect on the handled portion of a hand-ascender to create an haul and rope grab system. No need for an expensive tool if you can combine two common pieces and do the same.

FYI – The name Katrol comes from the Dutch language and means pulley. It is a wink to a country as a sea faring nation. Lots of rope access is happening in the North Sea so you don’t need a mountain to climb these days.

Being in Canada we do understand the need for good reliable mountain gear. This is where we strived to find a balance for a lower weight but also its efficiency.

Altogether we feel it is a great product and well priced. We hope you will enjoy it for a long time.
