7075 Aluminum replacement spools/pulleys for the venerable Petzl Simple descender. These 2-hole spools replace the upper position spools of older Simples (pre 2019). Made of 7075 aluminum, these replacement spools last about 2x as long as the stock 6061 Aluminum spools. They offer similar friction characteristics to the stock spools. These make a great upper position spool to pair with our 316 Stainless Steel spools, or pair with one of our 1-Hole 7075 Aluminum spools to maintain the light weight and/or to preserve the original friction characteristics of your Simple. Each spool weighs approximately 51 g (1.8 oz). We also make 316 stainless steel (smoother ride and much more durable than stock). These spools are in use all over the world and hand made in the USA. The 2-Hole versions are more time consuming to manufacture due to the off center mounting holes, and thus cost a bit more than the 1-Hole versions.
It is, of course, your responsibility to familiarize yourself with your new spool(s) (and any other changes to your vertical setup) in a controlled setting prior to real world use. Replicate all conceivable scenarios you might encounter (wet/muddy rope, thin/fat rope, new/old rope of various materials, etc). Make sure your setup works to your satisfaction, your life depends on it! If you aren’t happy with the performance of your spool(s) after this step, you may return them.
All spools are tested for fit and function prior to shipping, please excuse any resulting minor cosmetic imperfections that may result. Serial numbers may be laser engraved or stamped.
Speaking of which, If you so desire we can add limited simple custom text to your spool(s) e.g. your name/NSS #/organization/ID# for clubs, etc. Reach out through email.
Still have questions? FAQ’s! Feel free to send us an email! Thanks, and happy caving!
