This exciting new zipper is sure to make your boating life easier and save you money. It's easy to use, just cut to length on your boat!

Evaluate Your Old Zippers!

  • Run your fingers across the zipper teeth. If the teeth feel crumbly and your finger comes away chalky, it is definitely time to replace. If your teeth have eroded and look small and are without definition, replace the zipper.
  • If the zipper has broken or missing retaining box or pin, replace the zipper.

EZ-Xtend Boat Zippers can be a helpful repair when your old zippers are still in good condition, so it is important that you take the time to evaluate the old zippers.

Important- EZ-Xtend boat zippers do not decrease the likelihood of zipper failure. They are designed to correct fit and provide other repair assistance.

IMPORTANT: Please determine your zipper teeth size accurately before ordering!
Please don't guess, #8 and #10 look very similar.

Here Are 3 Methods For Figuring Out What Size Zipper Teeth Are On Your Boat!

  1. Use the Actual Size Photo at the top of this page from any phone  or computer screen to figure out what zipper size you have right from your boat.  
  2. Use the form on the Contact us page and request a mini sample of both zipper teeth sizes and take them to the boat.
  3. Print PDF Actual Size photo, take it to your boat and follow the instructions.  Click Here for printable PDF!

Fantastic Results

"I wanted to thank you for the fantastic results I have with the EZ-Xtend zipper solution you provided for my Sea Ray.

The isinglass had shrunk to the point that installing it was an all-morning job, with some snaps totally unusable due to the material shrinkage. I really was preparing to purchase a complete new canvas set, but hated to spend the money-especially since the canvas is still in excellent shape.

The EZ-Xtend zippers have made the canvas/isinglass installation and removal about a 10 minute job! (and looks great too!) Thanks again for the quick solution and the reasonable cost, I really do appreciate it.
Steve Donovan

The Bottom Line

The extend zippers have been a resounding success. Zippers were needed for the starboard stern section of my bimini top, and for both side curtains of my camper canvas. It is a clever design you came up with to increase the width of connectivity between my bimini top and camper canvas sections. I do not know what I would have done otherwise as the camper canvas sections have shown shrinkage over time.

Such a Great Idea

I got a chance to install these yesterday and just thought I'd get back to you to let you know that they worked perfectly for me. I couldn't be happier with that simple to install solution to my problem now allowing me to properly and fully enclose my cockpit again. Such a great idea.

Easy to Install

The Ez-xtend zippers were very easy to install---especially with a little lubricant ( which I always apply periodically to zippers)

Rare Traits

"True skill and craftsmanship are rare traits in today's society. When they're held by a person that truly cares about her customers, brings honesty, creativity and passion to her work, you have just described Tammy Hampton. Better known as "The Cover Girl," Tammy has been both a friend, mentor and business partner for nearly twenty years.

I found Tammy by her name tag.... sewn to a sailboat cover, in a nearby marina. The boat cover was fitted with such precision, it clearly stood out from the others. In the years since, Tammy has 'dressed out' at least twenty boats for me. She has yet to meet a challenge for which she could not find a creative and effective solution.

Tammy has become a valuable resource to my Boatbutler business, and she has actually created sort of a "cult" following among my customers. Once they see the quality of her work, the choice is an easy one.

I am still grateful for that little tag on that sailboat cover I found nearly twenty years ago."

You Made Everything Easy

We just installed the zipper we received on our sea ray boat canvas- what an incredibly easy experience!  It makes snapping the canvas so much easier with the zipper extension.  Thanks for the crimper & tape - you made everything easy.  We just ordered 5 more longer ones to completely update our canvas.  Thank you so much for your quick response on our first order. 


Love Your Website

I love your website and wish we lived closer, so that I
could stop by your shop - sounds like a wonderful place!

Made our boating season very enjoyable!

Our boat was 10 years old when we purchased it and the canvas was stored all rolled up in the boat.   When we tried to put the canvas together the force required to zipper the canvas together was making the canvas split on the seams or causing the zippers to tear, so we had to leave parts of the canvas unattached and every time it rained we would get water in the boat.  With your zippers in place we could button up all of the canvas and make a very nice weather tight space which made our boating season very enjoyable.

EZ-Xtend Zipper Saved the Day 

I purchased a used 27' Sundancer about a year ago.
I came with the Bimini, side curtains & windshield eisenglass panels along with a bimini to transom cover with eisenglass also.
I don't think the original owner ever put anything up except the bimini.
Nothing would fit, ever where it was short. 
If I cheated and put the windshield panels in the side curtains were never even close. If I did it the other way, sides first front panels were off. The canvas is hi quality material from a well known manufacturer.
Started researching about what to do. Then I came across a blog on the Searay owners site. One of the chats was about what I had going on. One owner who replied had purchased your zippers and was raving about solving his problem using them.
Well I'm here to "RAVE" about them also. My $300.00 investment with you has saved me thousands in replacing what is perfectly good canvas.
Boaters if you have a shrinkage problem and we're not talking the George Costanza kind this is your answer.
Your site has also grown to include more helpful information on boat care and maintenance. Great information and wonderful tips.
Thanks again Ron W.
