Gun Facilitates Adhesive Bonding of Studs to Surfaces 
This tool will facilitate the bonding of thermo-
plastic-backed studs to smooth, hard surfaces (such as 
marble). Such studs can be used for mounting loads, 
such as heavy pictures or signs, on walls in public 
buildings where defacement with drilled holes cannot 
be tolerated. These studs can easily be removed, when 
desired, by softening the plastic bonding with heat 
from the gun. 
Design characteristics of the gun are as follows: 
I. Maximum wattage I KW at 50 volts ac or dc. 
2. Input êontrollable from external power supply (ac 
or dc). 
3. Operating temperature to 700° F maximum. 
4. Insulation protects user: exterior temperature rise 
does not exceed 36°F after 30 minutes operation. 
5. Spring is easily removed to permit spring-force ad-
justment. 
6. Standoffs interlock with trigger to prevent opera-
tion unless all standoffs are depressed indicating 
that the stud is perpendicular to surface.
7. Weight approximately 3 pounds.
