Hoisin is often referred to as Chinese barbecue sauce, not because it has a similar flavor, but because it is used for a variety of purposes, similar to American barbecue sauce. Hoisin is also sometimes referred to as Peking sauce because it is used to create the thick glaze on the popular dish, Peking duck.
Balusters, the vertical guards that support the handrail, must be installed close enough that the space between them is no greater than 4 inches. Most city inspectors carry a 4-inch ball with them to test the spacing. Installed balusters should withstand 50 lbs. of pressure exerted over a 1-square-foot area.
Back to the hardware stores, to look at what they stock. HomeDepot has the Williamsburg style columns like what is currently on the house. And their deluxe railing was very nice. They even had a nice stair railing kit. But one big problem, the railing the stock is only 5 feet 7 inches in length, as is their stair railing kit. The distance between the columns on my porch are (starting from the left) 6 feet 4 1/4 inches, 6 feet 3 3/8 inches, and on the right side 7 feet 4 inches.
