In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

About Product Overview

This 28 oz cartridge refill is made for Flex Glue Max applicators, giving you a non-sag paste adhesive that holds its position on vertical and overhead surfaces instead of running. It's rated super strength and bonds to most surfaces, indoors or out, with UV resistance for repairs that stay outside.

With a 10-minute working time and 24-hour full cure, it's suited for jobs that need a strong initial hold before you can move on. It handles application temperatures from 0 to 150 degrees Fahrenheit, so it's usable across a range of job-site conditions.

  • Container size: 28 oz cartridge
  • Form: Non-sag paste
  • Adhesion strength: Super strength
  • UV resistant, indoor and outdoor use
  • Working time: 10 minutes; full cure: 24 hours
  • Application temperature range: 0 to 150°F

Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.
