Arkon Robust Clamp Mount with Security Knob - 17mm Compatible

The Arkon RMCPM2517 Robust Clamp Mount is a genuinely adaptable locking clamp, built around a distinctive jaw shape that delivers an unusually wide clamping range across both flat surfaces (tables, desks, counters and shelves) and tubular ones (handlebars, roll bars, wheelchairs, strollers, grocery carts and golf carts), small posts included. It works with Arkon's range of 17mm ball compatible holders and adapters, sold separately. Supplied in the box you'll find a Robust Clamp Pedestal, a 25mm to 17mm ball adapter, one 3.75" Standard Robust Mount Shaft, one 2.75" Small Robust Shaft, plus the optional security knob and hardware. Construction combines high-strength composite materials with corrosion-resistant stainless steel hardware, and the clamp goes on and comes off without tools on flat panels as well as round, square or irregularly shaped bars and rails. Pick whichever of the two included shafts — 3.75" or 2.75" — best suits the space you're working in. Clamping capacity covers tables, desks and similar surfaces from .2 inches to 1.75 inches (5mm to 44.5mm) thick, or handlebars, posts and wheelchair tubing from .25 inches to 2 inches (6.5mm to 51mm) in diameter, and it doubles nicely as a microphone stand mount.
