The double locking PTRi adjustment runners are recommended for road use in cars without a bulkhead.

These heavy-duty runners allow a very small footprint and have been made to allow the seat to run as low as possible on a flat floor.  All Tillett runners are designed to sit in the gap that exists under the seat base, without raising the seat dome in which the driver sits. This is especially useful in vehicles with low roof heights where a roll bar or crash helmet may reduce the available space further.

They have a 31.5cm hole spacing front to back and side to side, matching our bracket types which bend under the seat. They can also be used on the wider based XL, B8 and B9 seats by bending the handle a little.

The PTRi also has a second hole option of 34.5cm, which helps when using other makes of longer brackets.

KEY FEATURES

• Compact runner set designed to sit under the INWARD pointing Tillett bracket sets such as STBI & PTBI, for a minimal footprint within narrow and restricted cockpits. They also work with the B5 brackets TBB5 and TBB5T inwards.
• Almost twice as strong as the light weight STRi.
• Made from steel with a black paint finish.
• The use of a TK5 fitting kit is advised to fit the PTRi to “bottom mount” seats, and the kit includes nylon spacers to adjust the angle and clear the mechanism from touching the composite.
• Each runner set weighs 2.2 kg.
