USE OF DECORATIVETREAD BRACKETSWhen using Coffman’sdecorative tread brackets(C-8028 or C-8029), the risermark must be adjusted onthe skirtboard by thethickness of the 1/4" bracketto allow the bracket to bemitered. PHOTO 4-25.Each riser line can bemanually moved into thestair by 1/4" or a skirtboardmarking jig planed to thethickness of the riser stockless the thickness of thebracket (3/4" - 1/4" = 1/2")can be used (See Chapter 4,Page 8).To prepare the bracket forinstallation, cut a 45° miteronto the riser edge.

Temporarily positiontwo brackets in place andmark the back of the lowerbracket to align with thedrop of the bracket above.PHOTO 4-27.45° CUT4-254-26Trim the brackets to thenecessary height and installwith carpenter’s glue andfinish nails. PHOTO 4-28.NOTE: Because any crackbetween the bottom of thetread and the top of thebracket will be concealed bythe cove moulding(See Photo 4-55), it issometimes easier to achievea better miter at theskirtboard/riser joint whenusing a decorative treadbracket. This fact, coupledwith the desire by somehomeowners for a moredecorative finished stair,makes tread brackets anoption that should beconsidered on every job.10 CHAPTER 4 - STAIR BODYTRIM TO HEIGHTMARK AND TRIMTO LENGTH4-274-28C O F F M A N S T A I R P A R T S • S I N C E 1 8 7 4
