Frequently Asked Questions

Maintenance
Q: Do zippers need to be lubricated?
A: Metal tooth zippers can be lubricated to allow easier “meshing” of the metal teeth. Zippers are a mechanical device much like a gear. Occasional lubrication of metal tooth zippers is perfectly acceptable. Use a wax like product or even a candle to apply directly to the metal teeth. Do not use a spray lubricant. Plastic tooth zippers (either molded plastic or coil) should NOT be lubricated. Lenzip molded plastic zippers are made from DuPont Delrin® acetal resins. These resins are very strong and need no lubrication. Coil zippers should never need lubrication.

Q: Can I make my own separating (open end) zippers?
A: No. The components at the bottom of an open end zipper are fastened to the zipper with specialized equipment that includes a punch press and dies made specific to the size and shape of the component. Attempting to attach these components without this equipment will result in a mis-formed component that will not allow the zipper to operate properly. Lenzip does not sell pin and box components.

Customer Service
Q: What is your guarantee?
A: All Lenzip zippers are guaranteed for the life of the zipper. Lenzip zippers are guaranteed against defective materials and/or workmanship for the life of the zipper. Any zipper returned and so found, will be replaced by a new zipper free of charge. Our liability in connection with the use of Lenzip zippers is limited, however, to the value of the zipper.

Q: What is your minimum order?
A: Minimum orders are based on the gauge and style of the zipper ordered. Typically, the minimum would be 50 pieces of exactly the same style, length and color. Smaller gauge zippers would require a 100 piece minimum of the same style, length and color. Exceptions to minimum order requirements would be zippers of an unusual length or configuration.

Q: What is the difference between the companies, LENZIP and ZIPPERSOURCE?
A: LENZIP is a full line manufacturer that sells to companies that require a higher volume of the same zipper. ZIPPERSOURCE is America’s #1 source for small quantity, custom made zippers. If needs call for just one or two custom made zippers, ZIPPERSOURCE can offer all the same products that LENZIP offers, in quantities as few as one.

Q: Do you stock zippers that are already made?
A: Lenzip stocks zippers for immediate shipment for the marine industry. These zippers are #8 and #10 molded plastic zippers in standard marine lengths and made with standard marine sliders. All other types of zippers are made-to-order due to the thousands of various materials, colors, length and slider choices that are available. Standard lead times will prevail for all non-stocked cut-to-length zippers.

Q: Tell me about custom logo sliders
A: Lenzip can create a custom logo slider. Clean artwork is required in disk format and costs depend on the complexity of the logo. Samples would be submitted for your approval prior to the production run. There is a one-time, non-reoccurring cost to produce the mold necessary to create the custom pull. Costs for such molds are quoted indivually, based on the tooling required. Minimum orders are required for production runs. These minimums may range from 10, 000 pieces to 25,000 pieces depending on the size/shape of the pull. Costs for such custom pulls are quoted individually.

Q: Can Lenzip dye-to-match?
A: On large orders, we can accommodate a certain color request. We do not provide sample dye lots or provide special order colors on small quantity runs of non-stocked colors. Please refer to our color list for our standard colors.

Q: Where are Lenzip zippers made?
A: Lenzip zippers are assembled in Rolling Meadows, Illinois, a Chicago suburb. Much of the raw material used to make Lenzip zippers is manufactured in the United States. There are some small components used on certain zippers that are from foreign sources.
