The Raypak 006885F Thermostat Knob Kit is an OEM replacement control knob designed for numerous RP2100 series heaters and related Raypak models (such as the 183, 263, 333, 403 series). This knob directly interfaces with the thermostat shaft, allowing users to adjust set-point temperature precisely. Made from durable molded materials to resist heat, UV exposure, and frequent handling, it restores tactile feedback and control lost when original knobs become worn or stripped.
