  gear4rocks is a small Ukrainian manufacturer of climbing gear whose passion for the pursuit of excellence in traditional climbing equipment began in the early 1980's. The founder and owner of gear4rocks, climber and lead designer, began manufacturing a wide range of passive climbing equipment from his own enthusiasm for climbing. Today after 20+ years of experience, the gear4rocks product portfolio consists of various camming devices (flexible friends), stoppers (rock nuts), various belay devices, pulleys, crampons and a lot of other great climbing gear.

We have been selling rock climbing gear online since 2006. Over the years, we have sold thousands of pieces of gear4rocks climbing gear to customers in the United States, Canada, United Kingdom, Australia, Italy, Spain, New Zealand and many other countries around the world. Check out our excellent feedback! Aside from local climbing shops throughout the Ukraine and Russia, gear4rocks climbing equipment is only available through our bonanza booth and the gear4rocks website.

  gear4rocks was created to fill the needs of the Ukrainian and East European climbing community. These are hardy climbers who don’t care what their gear looks like and they would never, nor could ever, drop $500+ for a set of cams. They just want safe gear for cheap. Over the years our customer base has grown to include many search & rescue groups and military. These groups want gear to hold the forces they are rated for, function smoothly and that is it. No pretty colors. No shinny finish. No big star rock jock advertisements in magazines. gear4rocks has made climbing gear affordable for normal people who want a cheaper alternative. We are happy to hear the positive feedback many of you have given us over the years. Our gear is designed to be functional, serviceable, affordable and safe, not pretty or trendy. We promise to keep it that way.  

  All equipment has been tested by "STANDART" the Ukrainian National Scientific-Certification Center in Kiev, the capital of Ukraine. Testing procedures are based on CE and UIAA standards. For Personal Protective Equipment (PPE) to be legally sold in Ukraine it must be tested by "STANDART." Upon your request we will scan and email you the image of the original testing certificate (Russian language).

All gear is manufactured from the highest quality materials and is assembled by qualified engineers under the supervision of experienced quality controllers.

The "strength" rated in the table is the maximum load a piece of equipment can take without sustaining damage. In the case of overload and damage it is important to retire that gear. Do not try to repair gear4rocks equipment.

As part of the gear4rocks quality control, each device is loaded to half of its maximum rating. Before it leaves the factory each device is reinspected to ensure that all components are working appropriately.

The gear4rocks links cams have passed CE certification. We will now be working through the UIAA or CE certification process for our other lines of equipment. As resources and time allows we hope to gain additional certifications for all of our gear. Unfortunately at this time we are unable to determine how long it will be before paperwork & testing processes are complete. Upon completion of CE and UIAA testing, certificates will be issued with the appropriate safety labels and the gear4rocks bonanza listings and gear4rocks web site will be updated to reflect the endorsement.
