Skeleton Sealant Gun for Cartridges up to 310ml, Steel Frame

A steel skeleton gun for standard cartridges up to 310ml. It takes standard cartridge-format adhesives, fillers and sealants, and is commonly used with our solvent free grab adhesive to secure anti-slip nosing to stair treads. The open cradle lets you see how much is left in the cartridge, and the trigger drives a steel push rod for a steady, controlled bead. The price shown is for one gun.

Why choose this gun

Takes standard cartridges. It suits all standard cartridge-format adhesives, fillers and sealants up to 310ml, so one gun covers most site work.

Open cradle. The skeleton frame lets you load a cartridge quickly and see at a glance how much is left.

Steady bead. Squeezing the trigger advances the push rod, so you can lay an even bead along a nosing, a sill or a joint.

Quick release. Pull the rod back by its hook handle to change cartridges, and to take the pressure off when you stop.

Simple and robust. A plain steel frame and rod, with nothing to charge or plug in, make it easy to keep in a site kit.

Where it is used

Fixing stair nosings, bonding skirting boards and sills, sealing window and door frames, filling joints, and general site and workshop use.

Specifications

Is this the right gun?

A skeleton gun like this suits standard cartridges up to 310ml. Larger sausage packs and 380ml to 410ml resin tubes need a different applicator.

How to use it

Pull the push rod fully back by its hook handle and lay the cartridge in the cradle, with the nozzle through the front. Cut the nozzle at an angle to suit the bead you want, and pierce the seal if the cartridge has one. Squeeze the trigger with a steady grip and move along the joint at an even speed.

When you stop, release the pressure by pulling the rod back slightly so that the cartridge does not keep oozing. Wipe the gun clean before any adhesive sets on it, and keep the rod free of dried material so it continues to run smoothly.

For stair nosings, run one bead along each inside face of the nosing, keeping the bead a little back from the edges so that it does not squeeze out onto the grit when you press the nosing into place. Work on one length at a time so that the adhesive stays fresh, and keep a spare cartridge to hand so that you can finish a flight without stopping. A cloth and a suitable cleaner will deal with any squeeze-out while it is still wet.
