Alpha – Base rails
• Base rail 7/49
(Ix = 7 cm4; profile height = 49 mm; weight = 1,0 kg/m)
• Base rail 13/58 ; 1.2 kg/m
• Base rail 19/63 ; 1.4 kg/m
• Base rail 25/65 ; 1.73 kg/m
• Available in 3.0 m, 2.4 m, 1.8 m, 1.2 m, 0.6 m (for large projects: 6.0 m on request)
Stand 110119
Alpha – Splice
• Connection between the rails
• Corresponding splice for each base rail
• Splice 7/49
• Splice 13/58
• Splice 19/63
• Splice 25/65
• Easy fixation of the splice behind the base rail
Stand 110119
Alpha – Telescoping end-piece
• Accuracy without cutting
• Identical static values as corresponding base rail
• Prolongation of the base rail: 6 to 66cm
=> 100% stockable and time savings
