How Many Types of E Type Rail Elastic Clip Are There?
E-type rail elastic clips have developed various model specifications based on international standards and application requirements, primarily classified by diameter size and applicable regions.
In terms of diameter specifications, different sizes from 16mm to 23mm form a complete product series. The E1609 type features a 16mm diameter design with a single piece weight of approximately 0.43 kg; the E1809 and E1813 types use 18mm diameter material, weighing 0.61 kg and 0.62 kg respectively; while models like E2001, E2007, E2009, E2039, E2055, E2056, and E2063 uniformly adopt the 20mm diameter standard, each weighing 0.80 kg. These different diameter clips correspond to varying load capacities and application scenarios.
