The Arrow TR550 is a heavy-duty high-temperature hot melt glue gun that heats up fast and delivers superior bonding for demanding jobs. A lever-feed design improves glue-flow control and reduces hand strain, so you get smoother output with less fatigue on longer sessions. It accepts both all-purpose and slow-set glue sticks, letting you match the adhesive to the project, and its double glue stick capacity means you can load one 10-inch full-size stick or two shorter sticks for fewer reloads. Compatible Arrow glue sticks, sold separately, include the AP10-4, AP5, and BSS6-4. The lightweight, ergonomic body keeps the gun comfortable to hold and control through crafts, upholstery, and general repairs. Between the lever feed, the flexible stick options, and the high-temperature output, the TR550 is a strong pick for serious hobbyists and tradespeople. Corded power keeps heat steady with no battery to recharge.
