Answer: Your vinegar should be fine, provided youâve been storing it properly. From a safety standpoint, commercially produced vinegar has a virtually indefinite shelf life, says the Vinegar Institute, an association that represents most of the worldâs largest vinegar manufacturers.nd itâs not unusual for vinegar to develop a haze or sediment, or to change color, after it has been stored for some time, says the Institute. Those changes in appearance do not make the vinegar unsafe to use, it adds.
The following analysis demonstrates results of a typical wood-framed stair stringer configuration as well as several similar configurations. Consider 15 risers at 7Â¼-inch tall with 10Â½-inch wide treads and stringers cut from SPF No. 1/No. 2 2x12s. This configuration results in an effective throat depth of approximately 5 inches for a horizontal span of 12 feet and 3 inches.
Because of this you should never space your stair stringers more than 16â on center. This means you will need to install a minimum of four stringers on any stairway wider than 36â. Always check the maximum span for your decking material as it applies to stair treads. Some composite materials and lower grade 5/4 wood decking may require you to reduce the stringer spacing to 10â on center. Always read the composite decking installation instructions for stair treads before building your stairs.
