SQWUREL - Extra Info
Vidoes are available to help demonstrate how to use the SQWUREL. More videos will be added when time allows.
SQWUREL Retirement due to Rope Grooving
Rope grooves created from normal wear will eventually get deep enough to force retirement of your SQWUREL. The recommendation for how deep the grooves can be before you retire your SQWUREL will change over time as the SQWUREL sees more use in the real world, testing is done and more is learned. To see the current recommendations, view the SQWUREL Retirement PDF.
SQWUREL Testing, Certification and Quality Control.
BG Gear recognizes the importance of testing equipment to ensure the quality and safety of the Sqwurel.
Each batch of Sqwurels are made from 7075 T6 / T651 aluminum. To ensure the Sqwurels are made from proper material, a metal certification test report is required of the manufacture which is kept on file with BG-Gear.
The SQWUREL is manufactured in an ISO 9001 compliant facility, which helps ensure the manufacturer produces exactly what was specified to be made.
Prior to public release one of the Sqwurel prototypes was rigged for rappel and pull tested to failure which occurred at over 3700 pounds of force (the failure point was the rope itself where it wrapped under the carabiner, not the Sqwurel). The Sqwurel was designed with a larger cross sectional area around the throat than the two most common competing devices (the ATS and Pirana) to ensure the Sqwurel had sufficient strength. Also prior to public release 12 prototypes were given to members in the canyoneering community who used the prototypes extensively over the course of a year. Some of the prototypes were rope grooved from use to well beyond the 50% worn through point and continued to perform well. With this in mind BG gear felt it was safe to release the Sqwurel to the public. After obtaining the first batch of Sqwurels for public release BG Gear will continue to test the Sqwurel to ensure quality and safety.
For more information on thoughts about testing and certification as well as a close look at the forces the Sqwurel is subjected to when rigged, please view the SQWUREL Testing Certification and Quality Control PDF. To look over information and conclusions from actual testing, please view the SQWUREL Testing Diary PDF which will be updated over time to share any testing done. Both of these PDFs are a work in progress and will continue to evolve and have information added, updated and modified.
Along the way I got help from friends in and out of the community. A huge THANK YOU to those who helped in various ways like listening to my constant ramblings, helping me think through stuff, testing, sharing fabrication thoughts, legal advice, providing computer skills, sharing insights on how the industry works and other helpful morsels. In no particular order, I would like to express my sincere appreciation to Jesse Patchett, Sam Ornelas, Clarence Valdez, Todd Rentchler, John Write, Tracy Kwan, Mike Cressman, Matt Williams, Abby Wines, Mike Schasch, Malia McIlvenna, Tim Dowling, Tom Jones, Roylnn Serati, Hank Moon and Matt Brejcha. THANK YOU!
Why the Name SQWUREL?
SQWUREL is not some fancy acronym and does not stand for anything. While developing the SQWUREL, many shapes and sizes were made to test various geometries and configurations. A lot of these prototypes looked absolutely nothing like the final version of the SQWUREL. One of the versions along the way looked like a squirrel and no matter who I handed it to they said "it looks like a squirrel". Well the name stuck even thought the shape changed. Its cute but its just a name with no real meaning.
