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
