Panel Cap for 21 mm round hole, white

This cap is for the round 21 mm panel hole/cutout (21 mm diameter). It is for covering up the 21 mm round hole on the control box which is saved for future uses (like 1/2 EMT connectors, etc). If you have mistakenly removed the knockouts from your control box, which is for the 1/2 EMT connector, you can use this cap to cover it. 

One (1) piece of cap is included in this listing. Bulk of 5 and bulk of 10 options are available. 

Note: this cover will not completely seal the hole.
