Weighing just 5.3g and measuring 57.7mm x 36.1mm x 11.5mm, it adds virtually no bulk while delivering durable, lightweight performance. Whether outfitting a time trial rig or repurposing an existing Garmin mount, the Quarter-Turn Adapter offers seamless integration and mounting flexibility with the trusted security Hammerhead users expect.
