The Heavy Duty Pen Clip for Art Machines is a pen holder that fits on the Bantam Tools ArtFrame or Bantam Tools NextDraw. As compared to the standard pen clips that ship with those machines, the Heavy Duty Pen Clip is built of thicker-gauge metal and has a side-facing design.  Both features allow you to screw down harder onto a tool than you can with the standard pen clip.  It includes an optional and customizable weighting system as well: A bolt and set of nuts that you can, if you like, mount onto the Heavy Duty Pen Clip to add additional weight to help weigh down your tool. That's helpful when working with tools like charcoal or graphite that benefit from customizable pressure.

This clip features a new side-mounting design that ensures a firm grip on your mark-making tool. When working with the Bantam Tools ArtFrame, this potentially adds a little extra travel and clearance, since the pen-clamping screw points "sideways" rather than in the direction of carriage travel. Whether working with heavier instruments or ones that require consistent pressure, the Heavy Duty Pen Clip delivers reliable performance for precision applications with the ArtFrame.

Weight: Roughly 27 g without added mass

Optional weights can add up to about 70 g of additional mass.
