2" Duct Plug (50 mm)
A 2" duct plug is a snap-in low-density polyethylene (LDPE) seal that closes an open 2" (50 mm) conduit or duct, keeping out water, dirt, debris, and animals until cable is pulled.
The Innovative Plastics 2" plug (part 2250-020L) pushes into the duct mouth by hand; its tapered, ribbed side walls form a friction seal that resists wind, water flow, and backfill pressure, then pulls back out without tools so the same plug can seal and re-open a run.
Every plug carries a built-in rope-tie, so mule tape or a pull-line stays staged inside the conduit for the day the cable is finally placed. LDPE keeps its shape in heat and cold and shrugs off UV, so a plug left on an exposed 2" riser through a season stays flexible rather than turning brittle.
The 2" size fits standard 2" primary conduit and larger innerduct — order to the duct you are actually sealing. See the full temporary plugs range (1"–8") or our conduit plug sizing guide to match every size to a part number.

FAQ
Frequently asked questions
- What is a 2" duct plug used for?
- It snaps into an open 2" conduit, duct, or innerduct to keep water, dirt, debris, and animals out while the run sits exposed before cable is pulled. It installs and removes by hand.
- Does the 2" plug have a pull-line tie?
- Yes. Every Innovative Plastics temporary plug, including the 2" size, has a molded rope-tie so you can attach mule tape or a pull-line for future access.
- Should I size the plug to the conduit or the innerduct?
- Order to the trade size of the duct you are sealing. If you are plugging innerduct inside a larger host conduit, order the innerduct size so the plug seats on the duct it is protecting.
