The phrase "undercover work" doesn’t bring to mind images of a private detective in a fedora sleuthing in and out of the dark for the masonry contractor. Instead, these jobsite veterans see images of bricklayers and block layers on scaffolds or work platforms relying on plastic or fabric enclosures to protect them from inclement weather so they can work productively.

Work platform manufacturers usually have proprietary frames for their specific models. Scaffold manufacturers offer very few products for enclosure, but will discuss the topic with contractors and make recommendations. Enclosure manufacturers offer a range of materials for use on both work platforms and scaffolds.
