If You're Using a Ravioli Maker... Place the metal base of the ravioli maker in front of you and lay your first sheet of dough on top. Then, take the plastic mold and gently press down to form depressions in the dough. You want to work relatively quickly, so that your dough doesn't have an opportunity to dry out and become brittle.
Top edges of stair rail systems used as handrails must not be more than 37 inches (94 cm) high nor less than 36 inches (91.5 cm) from the upper surface of the stair rail system to the surface of the tread. (If installed before March 15, 1991, not less than 30 inches [76 cm]).
Bottom Line. Install stair handrails at the height suggested by national and state building codes, which is 30 to 34 inches. If no codes regulate stair handrail height in your area, you have the freedom to install the rails at a different height, but as suggested, 36 to 40 inches is the best for preventing falls.
