2024 transparent silicone gripper designed to lock the frame in position, avoiding miters shifting while clamping. It self-adjusts and fine-tunes the miter's angle and optimizes the surface contact, thus creating robust and precise bonding and a beautiful joint that feels and looks great. It is a user-friendly material that is manageable and stays clean.
Being transparent, Grubber allows more light to see the engagement of the clamp/frame and the slow action of joining in real time.
