Sometime in the 90s, Weber stopped using wooden handles on their grills and replaced them with plastic handles. Technically the handles are glass reinforced nylon, but typically referred to as plastic.
While the plastic handles are likely much more cost-effective and durable, the general consensus is that the plastic handles don’t dissipate heat as well as the wooden handles.
Give your Weber Smokey Mountain that classic look, by adding a handcrafted wooden handle.
Please note the 57cm WSM will require 2 handles and the 47cm just 1.
