Abstract: Structures for retaining one or more accessory tools to a caulking gun are disclosed. The structures are adapted to accommodate different accessory tools, such as spatulas, utility knives, hangers, handles, and flashlights. In one embodiment, the retention structure is a mounting rail affixed to the caulking gun, the mounting rail including an elongate body having a plurality of ribs oriented transverse to a major axis. In another embodiment, the retention structure is a housing affixed to the caulking gun and including a plurality of mounting rails positioned thereon. The housing may be formed of discrete components connected by a common hinge and may include an internal channel for retaining a hanger in different rotational positions. In another embodiment, a barrel strap may be used to secure multiple mounting rails to a caulking gun barrel. In another embodiment, a strap assembly is provided to enable hands-free carrying of the caulking gun.

Abstract: A nozzle assembly for dispensing viscous material is disclosed. The nozzle assembly is convertible from use with a device for dispensing bulk viscous material to use with a device for dispensing viscous material from a cartridge. Alternatively, the nozzle assembly is convertible from use with a device for dispensing viscous material from a sausage package to use with a device for dispensing from a cartridge. When dispensing viscous material from a cartridge, the base portion is arranged for receiving the cartridge conical tip and the flange is arranged for placement between an end plate of the dispenser and the cartridge to retain said nozzle within said dispenser for dispensing viscous material from the cartridge. When dispensing viscous material in bulk form or from a sausage package, a locking plate is provided for tightly retaining the nozzle to the end cap of the dispensing device.

Abstract: A nozzle is disclosed for dispensing viscous material comprising a plurality of dispensing tubes having dispensing tips and a single input cavity adapted to accept the viscous material. In an embodiment, at least one of the dispensing tips is manufactured closed and can be opened at the user's discretion. In a further embodiment, the nozzle has a flange at the input tube end, and the flange holds the nozzle between a dispensing tool end-stop and a material container, such as the tip of a tube of adhesive or sealant. In an embodiment, the dispensing tubes are at an angle to the centerline of the material dispenser. In a further embodiment, the nozzle screws into to a threaded socket on a dispensing tool by a thread on the outside of the input tube.
