ROTOCON LAB FRAME, Model BRZ33, 3 Ft by 3 Ft and 18 Inches Deep. This model exhibits the "Base Support Rod" design. Made of 1/2 inch round ASTM-304 STAINLESS STEEL solid rods connected and anchored by our tough Rotocon Zinc-alloy Assembly Clamps using nickel-plated steel nuts and screws. Sturdy construction with rod support, horizontally and vertically, at 12 inch intervals will accomodate medium to heavy loads providing a very strong lattice support. If this lab frame is too tall or wide for your space we can reduce the length of the rods to your specifications at no extra charge. Simply, send me a message, along with your order, describing your desired height or width and your order will ship within the usual 4 days. There are four anchoring bases which can be attached to your table top, fume hood base or floor to prevent tipping over. These clamps are designed for 10 degree increments of adjustment and will allow much versatility in design and construction. Detailed suggested assembly instructions for frames as pictured are included. The kit contents are as follows: 10 each 1/2 inch round stainless steel solid rods 36 inches in length, 2 each 1/2 inch round stainless steel solid rods 18 inches in length, 24 sets RT-1/2 Zinc-alloy Slip-On Assembly Clamps, 2 sets M-90 Zinc-alloy Mounting Base and 8 zinc-plated steel screws for anchoring.  Assembly required. Tape measure and flat blade screwdriver may be needed but not included in package. (This design also comes in various sizes up to 6 feet wide and 6 feet tall, with connectors made of Zinc-alloy, anchors made of Zinc-alloy or Aluminum-alloy, with rods made of 1/2" round tubular stainless steel, solid stainless steel, solid aluminum or white fiberglass).
