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.
Next you are going to install your 2x4's along the inside of the posts. Attach with screws. Now it is time for the balusters. Evenly space each baluster to the 2x4 with screws. Once those are all in place attach the top rail with screws. Now that the railings are in place we are almost done.
