* MADE FOR THE PROFESSIONALS - The new and improved SILIGUN PRO brings all the features of the classic SILIGUN to the professional end user. * MORE DURABLE - SILIGUN PRO has strong, yet lightweight aluminum body frame, and is made to work in the toughest scenarios. * THE MOST COMPACT CAULK GUN - At just 4" it's no bigger than the tube of caulk it's dispensing. Cut off the excess tubing to reach even tighter spaces. No more oversized, heavy caulk guns that limit your reach. * NO DRIP DESIGN - When you release the trigger, the flow stops. No more run-on mess that traditional caulk guns leave. * EFFICIENT DISPENSING - SILIGUN PRO has a powerful 24:1 thrust ratio and is suitable to work with any 10 oz tube (310 ml) on the market. *Not Suitable for Paper or Aluminum Tubes - Works best with Standard 10oz Plastic Tubes.
