Is there a part number for a solid red knob used on our push pull operators?
Harmony Push Button
The 9001R20 (1-3/8`` red mushroom) or the 9001R21 (2-1/4`` red mushroom) can be used for ``solid red`` buttons only.
When used on 9001KR9R or 9001SRK9R operators, 9001R20 and 9001R21 mushroom knobs must be used in conjunction with adapter ring 9001K54 which is available for the purpose at no charge.``)
