Double Frame Unibody Construction



The Best School Locker you will ever see, our third generation Marquis® Booksafe® locker now includes reinforced double frame unibody construction and a modern seamless deep-drawn stainless steel recessed handle. The industry's first and best single-point all-welded corridor locker just got better, stronger and more durable. We guarantee it with our lifetime warranty on all Marquis Booksafe III Lockers. Doors are provided without louvers for a clean flush front.

What is Unibody All-Welded?

  • Superior® unibody all-welded corridor lockers include our double vertical frame design adding strength, integrity, durability and visual appeal.
  • First we start with prime grade cold rolled sheet steel. 16 gauge for all body components except backs which are 18 gauge. Doors are heavy 14 gauge.
  • Sides are formed to be an integral part of the front vertical locker frame which locks into the bottom for precise alignment and added strength.
  • We MIG weld an additional channel shaped vertical frame member between doors providing a continuous door strike at both the hinge and latch side of the door.
  • The top and bottom are flanged downward at the front to form a 1-1/2" high channel shaped top and bottom horizontal frame member continuous across the multiple column unit up to 60" wide.
  • The base is a full 1-1/2" high keeping locker contents away from moisture on the floor and/or wood/concrete base.
  • Front-to-back channel stiffeners are welded into the base under each side panel providing a strong anchor bearing surface for installation and increasing overall unit strength.
  • Horizontal tier dividers for double and triple tier models project through to the face of the locker forming a horizontal cross member between doors for maximum strength.
  • Guaranteed in writing by our lifetime warranty.
