1 The original Waco Red premium frame scaffolding and shoring systems.

2 Waco is the First Name for Premium Scaffolding Waco Scaffolding is the first choice of those who demand maximum value for their equipment investment. Maximum strength, maximum quality, maximum life resulting in minimum annual cost of ownership. Check out some of our premium features that make Waco Scaffolding & Equipment your best supplier and Waco Red your best scaffold buy. Exacting Material Standards Premium quality starts with material standards that are so exacting that each load of tubing for Waco Red comes from the mill with certification that the steel meets our requirements for both yield and tensile strength. Rigorous Quality Standards Rigorous quality control procedures are followed through all three major production stages to ensure both accuracy and consistency: Machining Assembly Where the tubing is make into parts for assembly Where the parts are assembled in jigs and fixtures to maintain dimensional accuracy during welding. Finish Where the assembly is now painted using state of the art powder coating, that provides a more durable finish using paint formulated to Waco specifications. Strength By Design The superior strength and durability of Waco Red is realized through: Machined Tube Ends Each tube end that forms a weld joint is coped to provide a larger welding surface. Stronger Interior Members Note: Utilizing 11/4" OD tubing instead of 1" OD which is commonly used on lesser frames. All product drawings and information in this catalog are for illustrative purposes only and not to be considered in any way as an erection guide. 2

3 Excellence from the Beginning Since 1945 Waco Scaffolding & Equipment has been the standard by which others are measured when is comes to quality scaffolding. We provide America's top contractors and industry professionals with superior scaffolding solutions whenever and wherever needed. From the very beginning we've designed, manufactured and erected the very best scaffolding for thousands of satisfied customers who've come to depend on the Waco name. Fast And Safe On The Job Contractors rely on the standard features of Waco Red to improve their jobsite efficiency such as: Speedlocks The original Speedlock is a forged steel locking system that is considered by many to be the fastest, most positive lock available. Speedlocks are standard on all Waco Red Frames. Floating Pins Connecting Pins Standard Add to the speed and safety of erecting Waco Red Frames. This design allows one frame leg at a time to be placed over the connecting pin rather than wrestling the frame to align both legs at once. The pins have shoulders to maintain accurate alignment once in position. Ensuring that when you order Waco frames you have the correct pins to assemble them. Others attempt to artificially lower their frame prices by supplying the pins at an additional charge. Doing Something About Safety Full Range of Components Because we are concerned about the safe use of our products and the safety of our customers, each frame carries safety warning labels to alert workers to possible dangers and instruct them on proper procedures. Various size frames, braces, guardrail systems, casters, brackets and ladder or stair access are available to complete your access needs. 3

(See General Bracing and Detail) Braces must be fastened to each nailing plate with (6) 8d nails with at least one nail on each side of the mailing plate. Mail ends which protrude through the bracing lumber should be bent over, both for safety and added strength. The mails should be located so that they will not split either the bracing or the false work timber. Note: All double 2x lumber must be wedged in J head.

23 Scaffolding Safety Guidelines Safety guidelines As recommended by Scaffolding, Shoring, and Forming institute It shall be the responsibility of all employers and employees to read and comply with the following common sense guidelines which are designed to promote safety in the erecting and dismantling of scaffolds. These guidelines do not purport to be all inclusive nor to supplant or replace other additional safety and precautionary measures to cover usual or unusual conditions. Local, state, or federal statute or regulations shall supersede these guidelines if there is a conflict and it is the responsibility of each employee to comply. General Guidelines Post these scaffolding safety guidelines in a conspicuous place and be sure that all persons who erect, dismantle or use scaffolding are aware of them. Follow all state, local, and federal code, ordinances, and regulations pertaining to scaffolding because they may be more restrictive. For example, height or width requirements may vary. Survey the job site A survey shall be made of the job site or hazards, such as untamped earth fills, ditches, debris, high tension wires, unguarded openings, and other hazardous conditions created by other trades. These conditions shall be corrected or avoided as note in the following section. Inspect all equipment before using Never use any equipment that is damaged or defective in any way. Keep all equipment in good repair Avoid using corroded equipment the strength or corroded equipment is not known. Inspect erected scaffolds daily or at the beginning of every shift to be sure that they are maintained in safe condition. Never use equipment for purposes or in ways for which it was not intended. Report any unsafe condition. Never take chances Do not work on scaffolds if your physical condition is such that you feel dizzy or unsteady in any way. Working under the influence of alcohol or illegal drugs is strictly prohibited. Consult your scaffolding supplier Never take chances Consult manuals and instructions provided by the supplier; scaffolding is his business. Guidelines for Erection and Use of Scaffolding A. Provide adequate sills for scaffold posts and use base plates. B. Use adjusting screws or other approved conditions. C. Plumb and level all scaffolds as the erection proceeds. Do not force braces to fit. Level the scaffold until proper fit can be made easily. D. Bracing each frame or panel shall be braces by horizontal bracing. Cross bracing, diagonal bracing, or any combination thereof for securing vertical members together laterally. All brace connections shall be made secure, in accordance with manufacturers' recommendations. E. Do not climb cross braces, use only an access (climbing) ladder, access steps, from designed to be climbed or equivalent safe access to the scaffold. F. Tie running scaffold to wall or structure when the height exceeds four (4) times the minimum scaffold base dimension. The first vertical and longitudinal tie shall be placed at this point. Vertical ties shall be repeated at intervals not greater than 26 feet. Longitudinal ties shall be placed at each end and at intervals not greater than 30 feet. Ties must prevent the scaffold from tipping into or away from the wall or structure. G. When scaffolds are to be partially or fully enclosed, specific precautions must be taken to assure frequency and adequacy of ties attaching the scaffolding to the building due to increased load conditions resulting from effects of wind and weather. The scaffolding components to which the ties are attached must also be checked for additional loads. H. When free standing scaffold towers exceed four times their minimum base dimension vertically, they must be restrained from tipping. I. Do not erect scaffolds near electrical power lines unless proper precautions are taken. Consult the power service company for advice. J. Do not use ladders or makeshift devices on top of scaffolds to increase the height K. Do not exceed manufacturers recommended load rating. L. Equip and maintain all platforms with proper guardrails, midrails and toeboards along all open sides and ends of scaffold platforms. M. All brackets shall be seated correctly with side brackets parallel to the frames and end brackets parallel to the frames. Brackets shall not be bent or twisted from normal position.
