New to the auto-locking world, the Matik Belay Device features Camp USA's innovative Anti-Panic system to beat the competition in climbing safety. Anti-Panic disengages the double-hinged lever and applies the assisted braking cam whenever climbing ropes move too quickly through the device. This increases safety whenever climbers lower one another, rappel, or belay themselves. Also unlike standard auto-locking devices, the Matik's assisted braking cam runs parallel with the rope instead of at an angle, thereby increasing contact and decreasing rope-ruining friction. The wide carabiner hole has a unique design that prevents clipping and unclipping while the device is closed. Camp USA crafted this revolutionary device out of hot-forged aluminum and precision-cast stainless steel for the critical components that come in contact with the rope.


The assisted braking action of the Matik derives from an innovative camming design that makes the device safer and easier on the climber, the belayer, the anchor and the rope. Instead of using a blunt angle to pinch the rope abruptly when the cam is engaged, the Matik is built so the cam rotates in and comes in line alongside rope before it captures the rope completely. This alignment allows a much larger contact area between the cam and the rope (this makes the device more rope friendly than other auto-blocking devices), and the slight amount of slippage that occurs as the cam rotates into place reduce the impact force of a fall. This means less force on the bodies of the climber and belayer, and on the anchor! When lowering, the proprietary Anti-Panic system helps prevent one of the most common accidents occurring with the use of an auto-blocking device - losing control of the descent. The brake lever will automatically disengage causing the cam to automatically reengage if it is opened too quickly or if it is kept too far open where the speed of the descent can become unmanageable. This unique safety feature is particularly useful where there is little friction from rope drag between the belayer and the climber or during topdown descents where the Matik really delivers an unparalleled sense of safety and control. Users will also instantly notice that the Matik creates a very natural path for the rope that does not require looping or twisting of the rope during descent. Combined with the dynamic camming action that limits the impact of the fall, this more natural rope path helps to reduce wear and tear on the rope. Other distinguishing features of the Matik include a better method for inserting the rope that eliminates the possibility of clipping a carabiner to the device until it is completely closed. Features: - A revolutionary belay-descender device with assisted braking that delivers unparalleled safety and control - Gradual camming action reduces the impact force of a fall and decreases wear and tear on the rope - Proprietary Anti-Panic system automatically blocks the rope if the user loses control of the descent - Double-hinged lever and straight rope path make the descent feel very fluid and controlled - Intuitive design eliminates the possibility of clipping a carabiner to the device if it is not completely closed - Wide attachment hole allows the carabiner to rotate through the hole - High-end manufacturing with hot-forged aluminum main body and precision-cast stainless steel for the critical components that come in contact with the rope - For single dynamic ropes from 8.6 to 10.2 mm - Weight: 276 g, 9.7 oz
