Also the CF12107 variant. Same $4.49 CAD as AMRE Supply (likely the same parent company), so treat as one price point rather than two independent quotes.

About it
Thin foam pads that sit behind the cover plate of every outlet and light switch on your outside walls. Cold air pours in through the little gaps around electrical boxes, and six dollars of foam stops it in every room of the house.
Fitting it
Turn off the breaker, unscrew the cover plate, drop the foam pad on, screw it back - two minutes each, no other tools
Delivery
Flat envelope, under 0.1 kg - cheapest thing in the catalogue to ship · 0.1 kg
Approvals
Non-electrical accessory (sits behind the plate, does not carry current) - no CSA mark needed
Good to know
Sell in multiples - a typical house needs 30-40. Pack of 10 covers both duplex outlets and switches. Perfect free-shipping-threshold filler item.
