Skeleton Caulking Gun 400ml – Orange

This 400ml Skeleton Caulking Gun is a durable manual applicator designed for dispensing cartridge-based sealants, silicone, decorators’ caulk and compatible mastics smoothly and accurately.

The strong manual mechanism provides a 7:1 thrust ratio and approximately 1.2kN of dispensing force. This provides controlled application while reducing the hand pressure required to produce a consistent bead.

Its extended open frame accepts compatible rigid cartridges and tubes up to 400ml. This includes many commonly used 290ml, 300ml, 310ml and 380ml cartridges, making the gun suitable for a wide variety of sealing, decorating, construction and maintenance work.
