The Hatco 05.30.043.00 Warmer Pointer Knob provides precise, straightforward control for adjusting heat settings on compatible commercial warming equipment. Designed for use with an EGO infinite switch, this pointer-style knob transfers manual rotation directly to the switch shaft, allowing operators to select and maintain the desired temperature level. Its practical design supports consistent heat management during busy foodservice operations, while its durable construction is suited to frequent daily adjustments. As a replacement component, it can help restore proper control when an original knob becomes cracked, worn, loose, or difficult to turn. Confirm equipment compatibility, shaft configuration, and knob dimensions before installation for a secure fit and reliable operation.
