l-feet are available for 5/16" lag screws or 3/8" lag screws. They can be used with most popular mounting/flashing products for composition shingle and shake shingle roofing and provide an economical, high-strength base for the Alpha system. Tile and slate roof hooks are fabricated from high-grade stainless steel. The Alpha Ioof hooks are designed to facili- tate installation on existing roofs. Flat tile roof hooks are adjustable to two riser heights allowing them to be used on tile roofs installed with or without tile battens. The curved tile roof hooks are designed so that the rail mounting riser can be moved to position the niser in the valley of the tile while still allowing the base of the roof hook to be secured to a joist or rafter. Hanger bolts are available for use on corrugated and flat- panel metal roofs and for use with wood or metaJ rafters or purlins. Hanger bolts include an L-foot preassembled with [ail attachment hardware.;An EPDM rubber washer seals the hanger bolt against water intrusion. Alpha roof attachments · Rail attachments for virtually any zoof type · Preassembled with rail attachment hardware · High-grade stainless steel ensures strength and durability · Work with all Alpha rail types Base rails The Alpha system comprises foUI distinct sizes of alumin;um base rails. This allows users to choose a rail size that optimiz- es the balance between rail attachment frequency and rail cost. Larger, higher-strength Iails are capable of spanning larger distances between roof attachments but, because they are strengthened by additional metal, they cost somewhat more per foot than lighter rails. Lighter rails cost less per foot but may need to be attached more often.With foutrail weights from which to choose, Alpha gives system designers the ability to optimize based on environmental loads, labor costs and system layout. Alpha rails are designated 7/49, 13/58, 19/63 and 25/65. The firstinumber is an indication of the rail's relative strength. The second number is the height of the rail in millimetem. Module clamps and roof attachment components are identi- cal for all founail types which make parts availability and inventory management simpler and more reliable for dis- tributors and installers alike. Rails are available in standard lengths ranging from 2 feet to 12 feet in 2-foot increments and 20 foot lengths. Stan- dard length rails can be used to accommodate any number of modules and are intended for use with standard Alpha splices and the Alpha telescoping rails for precise, aestheti- cally pleasinginstallations.Alpha Tailored Rails are available in lengths conesponding to 2,3,4 or 5 standard 60-cell modules with a maximum width of 3'-3.5" (1004 mm) including end and inter-module clamps.Tailored Rails are ideal for larger projects where installation speed is para- mount andia small ambunt of rail projecting beyond the modules is not critical. Mounting Systems can also swpplY rails cut to custom lengths up to 35 feet.1 Minimum order quantities apply. Please con- suit Mounting Systems for more information. Mounting Systems also makes Alpha rails available for bulk purchasing, making it an even better value. Please consult Mounting Systems for quantity and pricing information. All Alpha rail is available in black anodizing for aestheti- cally sensitive applications. Black anodized module clamps and other Alpha system accessories such as telescoping end pieces are al5O available. To finish off the Alpha rails and make installations even more aesthetically pleasing, rail end caps are available to cover the.rail ends acid hidethe unfinished metal exposed during rail fabrication. End caps can be customized with your company's logo or ofher graphics, at nominal additional cost.
