| The position of the spectacle plate
indicates whether the line is open or closed, reducing or
eliminating the possibility of costly or dangerous
situations. Keckley Quick Acting Line Blinds utilize O-ring
seals to achieve the most effective shutoff. Our standard
O-ring is located in a dovetail groove in both faces of the
spectacle plate.
Two stainless steel guide pins are
located in the face of the body flange to ensure accurate
alignment of the spectacle plate with the bore.
With the Keckley Quick Acting Line Blind,
one operator can change a 6" Line Blind in five minutes
without the need for special tools as compared to a typical
6" spectacle blind, which takes two maintenance men
approximately 1-1/2 hours to change over.
