Stair Railings. Guard rails are required on the sides of stairs with a total rise of more than 30 above the floor or grade below. On this project we used Deckorators aluminum balusters, stair connectors, post caps and rail connectors.

Why is DMSO a good solvent? By the structure, DMSO seems to have a nucleophillic oxygen atom, electrophillic sulfure atom, so how can it be used in chemical reactions like substitution reactions? All about Solvents: Non-Polar, Polar Aprotic, and Polar Protic Solvents. This reference explains that it is polar aprotic and is suitable for SN2 reactions.
