17 years ago the first LINE2design firefighter door and sprinkler wedges were launched. This small but practical design is something that is needed by every firefighter. The door and sprinkler wedges were specifically designed to hold a common self-closing door by putting the small wedge at the top of the door and jamb. This unique design works amazing as a fire sprinkler stop as well. With the inception of the firefighter door and sprinkler wedges came the traditional all black heavy duty custom rubber fire helmet band to hold common accessories to most fire helmets. In addition to these firefighter helmet accessories, LINE2design is proud to say we invented the very first USA firefighter helmet decal set. Every one or the USA triangle and tetrahedron flag sets is double layered with 3M highly reflective material and hand cut. This was created out of respect for all those who lost their lives during the events of 9/11. Don’t get fooled by cheap copycat single layer printed designs that are on the market today.
