It is constructed from the strongest and most durable materials in the industry for dependable performance you can count on for years to come. Because this understructure has few moving parts, trouble-free operation is assured with routine maintenance.  \n 1  Sway Braces: All Interkal seating systems are stabilized by sway braces attached to the vertical columns and steel risers for maximum strength and resistance to movement. (Sway braces not required on rows 1 and 2.) Sway braces fabricated from steel are essential for vertical post bleachers to resist the compression and tension forces created when the bleachers are loaded.  \n 2  Vertical Posts: Electric-welded continuous 2” x 3” closed seam, rectangular structural steel tubing produces the strongest and safest vertical columns. Post size increases depending on row height and load-bearing requirements.  \n 3  Deck Supports: Deck support brackets are more rigid than competitive designs to help prevent sagging and potential binding during operation. All deck supports incorporate rollers for efficient operation and deck stability.  \n 4  Nose Beam: All Interkal seating options incorporate a structural continuous galvanized nose beam, resulting in a uniform understructure. This component provides superior strength, continuous support for the plywood deck, and the flexibility to achieve any aisle location/ configuration.  \n 5  Superslide System:  \nThe low-friction flexible rod system guarantees positive engagement of vertical supports without binding, assuring smooth operation over uneven floor conditions. The superslide system maintains proper vertical column spacing, reduces wear, and helps eliminate racking damage.  \n• Stabilize the bleacher under load in the extended position by securely locking each support post to an adjacent post.  \n• Automatically engage and release for opening and closing  \n 7  H Beams: The aluminum “H” Beams located at every plywood joint provide continuous support from rear riser to nosebeam. It also facilitates ease of cleaning by eliminating unsightly gaps.  \n 8  Wheel Channels:  \n• Wheel channels accommodate 8 to 12 wheels per channel for maximum weight distribution and operating ease.  \n• Wheel channels are precision formed from a single piece of steel coil for maximum rigidity.  \n• Heavy-duty composition rubber wheels are provided in a 31/2”diameter by 11/8” tread width.  \n• All wheels are provided with a 1/2” diameter steel axle secured with tamper-proof retaining rings.  \n• Wheels are equipped with oil-impregnated sintered metal bearings to assure smooth operation.  \n 9  Deck Support Rollers: Nylon rollers at the top of every deck support minimize friction for smoother, quieter operation and enhanced deck stability. Our rollers eliminate steel-to-steel contact which would hinder the operation of the bleacher.  \n10 Riser Beam:  \nMulti-bend component provides superior structural integrity.  \n11 Section Joints:  \n18” steel plates at every nose and riser to ensure the most rigid section joint available  \nSafety Features  \nSafety is the first and foremost concern in each and every Interkal design. The following key safety features are available:  \n• Limit switches on non-friction automatic power systems  \n• Plastic covers at every nosebeam exposed end and/or handicap location  \n• Removable pendant control attaches to the front of the seating system for added visual safety during operation of all automatic power systems  \n• Superslide System to insure positive engagement of all vertical posts  \n• Rear closure panels to  \n6  Row Locks:  \n\n| Interkal supports the NFPA-102 mandate for annual bleacher inspection and maintenance.
