Building your own subwoofer enclosure? This port tube features a rolled flange to ensure a clean fit on the outside of your box. The tough ABS plastic tube features markings that make it easy for you to trim the tube to the proper length for your driver and box combination.

It fits perfectly tight like I like it. Not as soft as the original but much more durable. It popped right in and I finished very fast! Great product.
Well its a port tube, but a quality one. Easy to cut to your desired length, the flange on the top will cover up any "not so perfect cut out hole", but i used a hole saw to cut the hole for it.
Overview: This is a plastic port tube used for ported enclosures for subwoofers.
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team. They verify what’s in the box, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.
I forwarded your question to an Advisor and they responded with the following: I do not show that this product is recommended for a particular box. Given that it is only 4" long, I don't see why it wouldn't work in any size custom box build. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy Jan 20, 2015 ] Staff
