The RAP-S-KNOB3-5U consists of a 1/4"-20 female threaded security knob and key knob. The RAP-S-KNOB3-5U replaces all knobs on 1" diameter B size arms and mounts. The RAP-S-KNOB3-5U offers the ideal amount of leverage to properly tighten your mount to prevent slippage in heavy chop or in extreme vibration environments. With an emphasis on aesthetics and function, the RAP-S-KNOB3-5U is low in profile and only adds a small amount of additional bulk to your system when compared to the standard knob included.
At a fraction of the cost of currently available keyed locking knobs, the additional peace of mind and tamper resistance comes at a very affordable price. RAP-S-KNOB3-5U is the perfect accessory for keeping your mounted electronic device safe from theft and tampering.

Incredible craft with this chair. For the price point it could definitely be over double the current price. Comfortable, easy to assemble and excellent materials.

A good value for the money.
Number of Items: 1
Chair was very easy to assemble. It is a lightweight chair but not cheap. I find it comfortable and the controls work well. Extra bolts are provided which is a great feature. I find the adjustable back support excellent, the head rest moves a little to easily, but it is easy to adjust while sitting.

Overall good chair for a good price
Number of Items: 1
Comfortable chair, but there's a very slight lean. I haven't yet managed to track down what's causing it, but as I slowly spin around, I find myself tilting slightly forward, then left, then back, then right... I've removed the casters and then removed/reinstalled the "ring" of legs, so the next place to check is the connection between the post and seat.
