This is a Draper Tools soft-grip caulking gun designed to apply 380 ml sealant cartridges for general-purpose sealing, bonding and jointing. It is a pistol-style, open-frame caulking gun intended for one-handed use when dispensing silicone, acrylic, polysulphide and polyurethane sealants from standard 380 ml cartridges used across construction and maintenance trades.

The main body is formed from mild steel with a protective epoxy/powder-coated finish to resist corrosion and wear in workshop and site environments. The push-rod is a smooth steel rod with a thumb-operated quick-release lever, providing a controlled manual piston drive rather than a threaded feed mechanism; this makes cartridge changes faster and reduces drip when the trigger is released. The soft-grip, ergonomically shaped handle is moulded for comfort during extended use and improves control when applying continuous beads of sealant.

Compatible with industry-standard 380 ml cartridges and with sealants manufactured to common construction standards such as ISO 11600 and BS EN 15651, the gun is suitable for use with the typical range of commercial sealants and adhesives. It is produced under Draper Tools Group quality control practices and within ISO 9001-managed manufacturing systems, appropriate for professional and DIY applications.

Typical applications include glazing, window and door installation, sanitary work, general building maintenance, plumbing joints, HVAC sealing and automotive trim work. Trades that commonly use this style of gun include glaziers, plumbers, decorators, builders and maintenance engineers. The manual push-rod drive delivers reliable dispensing for both low- and medium-viscosity sealants while the quick-release helps avoid wastage and improves site productivity.

Key benefits are straightforward compatibility with standard 380 ml cartridges, a corrosion-resistant steel chassis, user comfort from the soft-grip handle and a simple quick-release push-rod that reduces drip and speeds cartridge changes. Duchy Fasteners keeps Draper caulking guns in stock as single items and in trade packs where available, and also supplies a full range of cartridges, nozzles and sealant accessories to suit site and workshop needs.
