It includes a mix of 2 #10 plastic double-head sliders, 2 single-head sliders, and 8 snap caps, offering flexibility for multiple repair scenarios.

Buyer’s Guide
What zipper type fits marine canvas best?
For boat canvas, plastic autolock or Vislon sliders are common due to moisture resistance and reduced corrosion risk. Metal sliders can work in dry, coastal environments but may corrode in salt spray unless sealed.
How do you determine zipper size?
Most zippers indicate size on the back of the slider. If not, measure the teeth width in millimeters. Common boat canvas sizes are #10 and #20. Align the slider with the tape width for a proper fit.
Should you replace the entire zipper or just the sliders?
If the fabric tape is torn, frayed, or the track is bent, replacement of the entire zipper is advisable. If the tape is intact and only sliders are sticking or breaking, a slider repair kit is often sufficient.
What installation considerations help longevity?
Clean the zipper area before replacement, ensure even stitching or alignment, and protect the zipper from salt exposure after installation. Consider applying a marine lubricant designed for zippers for smooth operation.
When to choose plastic vs. metal sliders?
Plastic sliders resist corrosion and are suitable for damp environments. Metal sliders are stronger but can corrode; reserve them for dry, non-saline conditions or ensure proper protective coatings.
What about long, heavy-duty zippers?
For long openings like boat covers or tents, long tracks (72 inches or more) can handle heavy use. Ensure you have proper fabric allowance to avoid binding and fit compatibility with existing flaps or edges.
FAQ
- Q: Are these zippers suitable for saltwater boats?
A: Plastic and Vislon options are typically better for salt exposure due to corrosion resistance. - Q: How do I know which slider size to buy?
A: Check the back of the old slider for a size number or measure the teeth width to match size (e.g., 1-4, 5-7, 8-10). - Q: Can I reuse existing tracks with new sliders?
A: Yes if the slider matches the track and the tape is not damaged. Misalignment can cause sticking. - Q: Do I need tools to install these sliders?
A: Some kits require basic sewing or pliers; others are snap-in sliders that slide on with gentle pressure. - Q: What is the best practice for maintaining zippers on boat canvas?
A: Regular cleaning, dry storage, and a marine-grade zipper lubricant help extend life and ease operation. - Q: Are there cautions for heavy-duty zippers on canvas?
A: Large, heavy zippers require careful alignment and sometimes panel rework to avoid binding or stress on the fabric.
