Spring-Lock Design

Kadant Johnson spring-locking elbows consist of the standard gravity-lock elbow and a spring-lock assembly. The spring-lock assembly consists of five parts:

(2) Pipe collars, stainless steel (identical parts)
(2) Collar straps (identical parts)
(1) Locking spring, stainless steel

 

Features of the Kadant Johnson spring-lock system:

  • The collars and spring are stainless steel, to avoid corrosion.
  • The spring-lock assembly can be assembled without any tools.
  • The pivot pins in the collars cannot loosen and fall out.
  • The straps are contoured to guide the elbow into the open position for easier removal.
  • The spring is located on the radial syphon pipe, to minimize the extension into the dryer.
