Strut Length/Panel Size Table & Formulas
You can cut triangle panels to ht any frame size. However, we've found that a little planning can save you trouble and can save you money by minimizing waste. So take a little lime to figure things out in advance.

  1. Decide on square end 2 x 4 struts (top table) or bevelled end 2 x 4 struts (bottom table).
  2. Choose the strut length.
  3. Look up hole spacing, inside or outside panel size (see Job #4 Option #1 or #2) and roof panel size.

NOTE: "E" must be the same for all 25 struts no matter how ends are cut.

E - HOLE SPACE

SL - SQUARE END STRUT LENGTH
SB - BEVELLED END STRUT LENGTH

NOTE: Each triangle has three equal sides.

For any other strut lumber length use these formulas for 2x2's, 2x3's or 2x4's to determine panel size.
  For 2 x 2 Lumber
SL = E + 3"
SB = E + "
IP = E + "
OP = E + "
RP = OP x 1.14
  For 2 x 3 Lumber
SL = E + 3"
SB = E + "
IP = E + "
OP = E + "
RP = OP x 1.14
  For 2 x 4 Lumber
SL = E + 3"
SB = E + "
IP = E + 6"
OP = E + "
RP = OP x 1.14
