Style F

Style F- for use in joints between new and existing vertical walls, between curtain walls and glass atriums, and other vertical building walls where the flange is part of the closure design. Style F can be surface mounted.

• Stainless steel flanges are 2 ¼ " double metal construction for improved rigidity. Stainless is the metal of choice where staining is of concern. Flanges are available prepunched for fastening ( ¼ " holes 12" o.c.) or unpunched. Other metal flanges are available on special order.
• Flexible rubber membrane bellows are black Neoprene. Bellows are available in black or white EPDM on special order.
• Available in 10'4" lengths.

Factory fabricated transitions are available to accommodate intersections between vertical Expand-O-Gard and horizontal Expand-O-Flash expansion joints.

Bellows size: As a rule of thumb, bellows size should be the greater of the nominal joint plus maximum anticipated movement or 1.5 times the nominal width. Use method yielding the greater size.
