Magnetic adaptor that fits the nose of a Structnail gas tool and holds a GTW25 25 mm washer in place while the pin is driven.
Small part, whole method
Without it you are holding a washer against a steel stud with one hand and firing with the other, overhead. The magnet holds the washer square on the nose so the fixing is one action and the washer lands flat. It is what turns pins and washers into a workable way of fixing membrane to a steel frame.
Fit
Suits the Structnail tool with GTW25 washers. Included free with a 10,000 pin and washer purchase through RM Industries, so ask us before buying it separately on a large job.

Common questions
What does the adaptor actually do?
It fits the nose of the tool and holds a GTW25 washer in place with a magnet while the pin is driven, so the fixing is one action and the washer lands flat.
Do I really need one?
If you are fixing membrane or insulation with pins and washers, yes. Without it the washer has to be held by hand against the stud, which is slow and awkward overhead.
Which tool does it fit?
The Structnail gas tool, used with GTW25 25 mm steel washers.
Is it included with anything?
RM Industries include a free tool and magnetic adaptor with a 10,000 pin and washer purchase. Ask us before buying it separately on a large job.
How many do I need?
One per tool. It is a tool accessory, not a consumable.
