The SCOSCHE TerraClamp vehicle clamp mount line was developed as a versatile Powersports mounting solution that features multiple mounting options for a wide range of applications. They are designed for maximum performance while securely mounting many of today's top mobile devices and powersports accessories. Many of the TerraClamps car phone mounts incorporate SCOSCHE's award winning MagicMount or MagicMount Pro XL magnetic Smartphone system. Built using quality materials such as 6061-T6 Aerospace grade aluminum and stainless steel hardware clamps are built for long lasting durability. They come complete with the bike or vehicle mount, base and mounting hardware. On select portable TerraClamp mount models you can even customize the mount by adding one or more 4.5 Inch extension bars and/or “Knuckles” which provide an additional pivot joint and 1.5 Inch extension that can swivel and rotate 360 degrees. TerraClamp is extremely reliable and a great mounting solution for powersports enthusiasts.
