A Better Bulkhead. Bilco is celebrating its 75th anniversary with improvements to its Classic Series steel bulkhead. Changes include a new low-VOC primer by Sherwin-Williams and gas spring lifters, which help raise the doors and keep them from slamming shut. The product comes in several sizes and two models to fit either flat or angled stairway walls. Prices start at about $500. Bilco, 800/854-9724, bilco.com.
