Drain Jar Lid

The lids are fastened to the underside of the unit by rivets....3 to each lid.
I used a cordless drill and small drill bit to drill through the rivets to remove the old lids and remains of the rivets.
The new lids are easily fastened back using a rivet gun ( about $20 in Lowes) using small 1/8th aluminum rivets.
No real problems.
1 thing to note is that the drill bit will pass through the old rivet by about 1/4 inch before it comes up against the upper level of the BBQ floor so do not drill any deeper.The aluminum rivets are easy to drill through and you will easily feel when the rivet is drilled through.
