This product is a Knob Assembly for use in select models of Dacor Cooktops.
Dacor/Samsung has replaced the common 72731 knob with this knob (700834). You will notice that it has a completely new look, but the stem length and alignment of the 700834 perfectly matches that of the 72731 knob.
Please be aware that Dacor is now owned by Samsung. Your Dacor parts may arrive in Samsung branded packaging but they are guaranteed to be new and original, genuine Dacor parts.
