Stair Railing Installation

SPECIAL NOTES ON STAIR RAILING

The stair systems are designed for the typical angles created by an approximate 7 in. rise/11 in. run with allowance for accepted

variation in components. The Classic stair system allows for a 30-36 degree stair angle. Building codes are very specic on allowable

angles and widths. It is very important to consult with your local building code ofcials and plan your stair layout accordingly. Ensure that

you leave adequate space for graspable hand rail if applicable. “Dry tting” intermediate post placement will result in easier and better

looking installations and may avoid placement of post mounting brackets in areas where screws cannot attach to the guardrail.

Determining the angle for the railing

□ Using a 2 x 4 over the steps to create a consistent angle,

place the bottom rail (1) over the 2 x 4 and mark the end

angles for the bottom rail.

Marking the angles

□ Align the top rail (1) on top of the bottom rail (2), ensuring

the baluster holes are facing each other. Then mark the

angle of the bottom rail to the top rail.

NOTE: Make sure that when the holes are aligned, the

stair angle is continuous across both pieces. The minimum

distance from post to rst baluster slot is 2 in. for clearance

from the brackets.

Cutting the rail angles

□ Cut the top and bottom rails at the marked angles to t

tightly between the posts.

□ Transfer the stair angle to the crush block and cut to the

desired length (consult your local building ofcial for the

proper spacing between the stair tread and the railing).

Attaching brackets to the rails

□ Insert the upper and lower top stair brackets (FF and HH)

onto the top rails.

□ Insert the upper and lower bottom stair brackets (GG and II)

onto the bottom rails.
