Dayton Superior C89 and C89L Heavy Duty Bridge Overhang Brackets are designed for maximum adjustment and strength to meet the rigors of heavy cantilever/overhang applications. The C89 bracket features 72" long, four inch horizontal channels and an overall vertical adjustment range of 27-5/8" to 66-3/4". The C89L bracket has 90" long, six inch horizontal channels and an overall vertical adjustment of 29-5/8" to 68-3/4". Both brackets come equipped with nail holes in the top of the horizontal channels for attaching 2x6 or 2x8 lumber (flat) and both brackets have built-in guardrail receptacles for 2x4 guardrail posts. The C89 and C89L brackets can be used equally well on steel or precast concrete bridge girders with the appropriate 3/4" C60 45° Pres-Steel Hanger (Type 9-A). The brackets can be shipped “knocked down” for easier handling and shipping and then preset on the ground at the job site.
