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 troubteand 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 er~ 2 ~4 5I,~utS (bottom table).
   
2. Choose the strut length.
   
3. Look up hole spacing, inside or outside panel size (see Job #4 Optior~#1 or#2) and oof panel size.
   

Strut Length/Panel Size For 2 x 4 Lumber Only
square end 2x4 strut length SL	hole space E	inset panel side length IP	outside panel side length OP	roof panel side length RP
4’ = 45”	45	51	54½	62 1/8
5’ = 60”	57	63	66½	75 7/8
6’ = 72”	69	75	78½	89½
7’ = 84”	81	87	90½	103½
8’ = 96”	93	100	102½	116 7/8
9’ = 108”	105	111	114½	130½
bevelled end 2x4 strut length SL	hole space E	inset panel side length IP	outside panel side length OP	roof panel side length RP
4’ = 45”	40¾	46¾	50¼	57¼
5’ = 60”	52¾	58¾	62¼	71
6’ = 72”	64¾	70¾	74¼	84 5/8
7’ = 84”	76¾	82¾	86¼	98 3/8
8’ = 96”	88¾	94¾	98¼	112
9’ = 108”	100¾	106¾	110¼	125 5/8

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.
INSET WALL PANEL	OUTSIDE NAILED WALL PANEL	ROOF PANEL

For any other strut lumber length use these tormulas for 2x2’s, 2x3’s or 2x4’a to determine panel size.
