1. In a solar collector having a housing, an absorber and at least two glazings in which the inner glazing is a film, wherein the improvement comprises:
- said housing supporting a glazing shoulder;
a plurality of tenter strips, of substantially right angle sectional configuration having a ball-like cross-section at one side thereof and a smooth contact profile arm at the other side thereof, a plurality of grooves formed in said glazing shoulder in which said tenter strips rest, disposed within said tenter strips said housing having the ball-like side thereof in hinged connection with said grooves to secure the film therebetween and the smooth contact side thereof extending downwardly in an initial position for contact with the film, and an outer glazing is uniformly superposed on the hinged tenter strips to uniformly press the tenter strips downwardly to a final position for the smooth contact side thereof to contact the film and stretch, position and secure the film as the inner glazing.
