Drain cover

I used this to cover the fill line on an underground oil tank. It works great. Keeps out the rain water

By Scott


Drive Over Drain Blocker

Fits as described. Seals the storm drain very well and helps me to sleep at night knowing that should something spill in our loading dock area, it will not make it into the storm drain. I have not had any drive overs yet so can't attest to how well it stands up to be driven on but it appears to be constructed to handle.

24"round drive over drain blocker

this product worked perfectly for the situation I ordered it for. They are covering the fuel fills in our yard. they were continuously getting filled with rain water when it rained (which has been quite a bit this year) and setting off my fuel alarms. Since getting these I haven't had a single alarm issue! Thank you New Pig!

Drain Cover PLR 330

This product was the perfect item for sealing off a leaking roof drain at our facility. The material that it is made of was able to seal out every bit of water. When the job was completed it was easily removed and ready for the next job. It can reused over and over again for many other jobs. Best of all it was not only shipped quickly but came just in time to take on our urgent need. This drain cover is ideal for most drain sealing applications. It was money well spent.
