Rail splices <br />The Alpha rail splice is, in fact, a short section of the cor- <br />respondingly sized Alpha rail. The Alpha rail is specifically <br />designed with a series of small rails and channels on the <br />back side. When the splice section of rail is turned 180° <br />these rails and channels form a complementary pattern <br />that allows the splice to slide into the rails and channels <br />on the rail itself. The benefit of this clever design is that the <br />Alpha splice provides a joint between two base rails that is <br />as strong as an unbroken section ofrail - there is no loss of <br />strength across the Alpha splice. Therefore, there is no loss <br />of span capability and no requirement to reduce span or add <br />another roof attachment because of the splice,2 The Alpha <br />splice is preas5embled with Quickstones and bolts making <br />splice installation fast and simple. <br />Telescoping end pieces <br />The Alpha telescope is another unique design feature of the <br />Alpha system. The telescoping rail allows the base rail to be <br />extended up to 24 inches. Thus the rail length can be set to <br />the precise length required without cutting. With the Alpha <br />telescope there is no need to carry a saw to the roof, no <br />metal fragments left on the roof and no scrap rail to carry <br />off the roof and dispose of. The telescopes both speed system <br />assembly and improve worker safety. Like the Alpha splice, <br />the tblescopes preserve Iail strength and do not diminish rail <br />span capability. The telescopes thoughtful design allows it to <br />be installed on either end of the base rail. <br />1=9 <br />1 10. ./ <br />4 4 / <br />/, 4 IN <br />'0-/ 14 <br />Base rail <br />Telescoping end-piece <br />loose short lail section on the telescoping end-piece <br />Roof connection <br />Fixed short rail section <br />Telescoping end pieces <br />· Set precise rail length with no cutting <br />· Enhances aesthetics and safety <br />· Simplifies and speeds installation <br />· Eliminates waste and scra p <br />a Base rail a <br />b Splice b <br />r <br />d <br />e <br />2 Note: Due to its unconventional foim, 7/49 rail uses a dedicated spike shape.
