The Monarch Ultra Lite Speed Caulking Gun is a great tool to have in your tool kit. It is considerably lighter than a steel caulking gun of the same type which makes it much easier to handle.
The Ultra lite easily connects the sealant cartridge to the gun via a unique style quick turn housing. This removable housing feature holds the sealant cartridge securely to the gun, especially when the pressure is released, ensuring the cartridge doesn't come separated from the gun. Great for working up ladders or on roof tops.

To swap over sealant cartridges, simply twist & lock to remove or install a cartridge.
