which ends up as the floor 185 of the scupper 117 shown in other figures the working surfaces include one or more assembly apertures 181 preferably a first width 225 of a first end is a same size as a width 229 of the second end the width 186 a of the scupper in fig4 a is the same as the widths 226 228 in fig4 d the squares having sides 230 231 are subtracted from the overall width 225 of a first side of the piece to get the first width 226 the second width 228 is similarly determined from the squares having a side 227 subtracted from the overall second width 229 a first finished distance 222 is less than an overall distance 223 along a first side of the material 221 a second finished distance 232 is similarly determined after removing the distance 227 based on the bend at the respective bend line 215 a first width 224 is preferably a same as a second width or distance 227 fig4 e illustrates a planar view of a square component that is used multiple times to complete an upper or working edge of the sheet material for the spa such as spa 100 of fig1 and the spa 200 of fig2 a fig4 e includes a first.
