What does this zipper door do?

It installs onto your boat's shrink wrap film to create a resealable access point, letting you walk in and out of the wrapped boat without cutting the film.

Which size should I choose?

Choose 36 inches for a tighter, single-person access point, or 48 inches if you need a wider opening for carrying gear or equipment in and out during the storage season.

What is the difference between the 800W and the 800B?

Both are 48 inch white zipper doors; the 800B is specifically sized and configured to replace the Dr Shrink DS-3648B, while the 800W is the standard 48 inch door for new installations.

Will this door match my existing white shrink wrap film?

Yes, all doors in this line are white to match standard white boat shrink wrap film.

Do I need to cut my shrink wrap to install this door?

No, the door is applied onto the film to form the access opening itself, rather than being cut into an already-finished section of wrap.

Can I open and close the door repeatedly during storage?

Yes, the zipper is designed for repeated use throughout the season for maintenance, ventilation, or loading, then reseals each time you close it.

Is the 800B a true replacement for the Dr Shrink DS-3648B?

Yes, the SWS-800 (800B) is built to replace the Dr Shrink DS-3648B directly, so it fits the same 48 inch opening for like-for-like swaps.

What tools or supplies do I need to install this door?

Installation uses standard shrink wrap heat-sealing methods to bond the door edges to your film; no special tools beyond your normal shrink wrap heat gun are required.

Model 775W 800W 800B (Dr Shrink DS-3648B Replacement)

The Shrink Wrap International Zipper Door gives you a resealable access point in your boat's shrink wrap enclosure, so you can walk in and out to check lines, run dehumidifiers, load gear, or perform winter maintenance without slicing open the film. Each door bonds directly onto the shrink wrap during installation, then zips open and closed as many times as you need through the storage season and reseals to keep moisture, pests, and weather out. The line covers a 36 inch opening for tighter access points and a 48 inch opening for wider walk-through doorways, including an 800B version sized as a direct replacement for the Dr Shrink DS-3648B door.

Sizes & Options

Pick the door width that matches how you and your crew move through the enclosure. The 36 inch door (775W) suits a single-person walk-through or a tighter access point on smaller boats. The 48 inch doors (800W and 800B) open wide enough to carry gear, coolers, or equipment in and out comfortably, and are the better choice for larger enclosures or frequent in-season access. If you are replacing an existing Dr Shrink DS-3648B zipper door, choose the 800B to match that footprint exactly; otherwise the standard 800W covers the same 48 inch opening for new installations.
