Underwater Hardware Packaging and Thread Styles

These durable little tags have everything a retailer needs to showcase products and ring up sales. On each tag you will find the
Perko name colorfully printed in blue, our figure number, a product description and the bar code for your scanner. There is even
a California Proposition 65 statement (where applicable) on the back. These tags are designed to securely hold on to the product
and hang from your standard peg hooks. And since the tags are small, you can also simply toss them into a bulk bin if you prefer.
Either way, the tags will stay attached, unlike stickers that fall off bronze parts. These tags are available on thru hulls, adapters and
several types of strainers. Look for the "DP" designation. Our “DP” Dealer Package for small items (like the smaller thru hull fittings
and tailpieces) will be a 5 or 10 piece bulk box with a bar code label on each individual unit.
THESE 5 OR 10 PIECE CARTONS CANNOT BE BROKEN. Larger items (like valves & strainers) will be available
individually boxed as a single unit standard package with a barcode label on the outside of the box.
To be sure the parts you receive are barcoded for Retail Sale, order either a “DP” version or a single unit standard
package.
