- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/GB-4101-1014-0300:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals.

## Description

This aluminum tube is able to thread onto the [Lead Screw Square Nut ](https://www.gobilda.com/3506-series-lead-screw-square-nut-8mm-lead-4-start-16mm-length/)and serve as an extension rod of a linear actuator. One of the two internal M12 x 1.25mm threaded ends can fasten to the [Lead Screw Square Nut ](https://www.gobilda.com/3506-series-lead-screw-square-nut-8mm-lead-4-start-16mm-length/)while the other is available for possible future offerings to thread into. The tube is able to slide inside of the 14mm bore of [goRAIL](https://www.gobilda.com/gorail/) and [goTUBE](https://www.gobilda.com/4103-series-gotube/) which can act as the linear actuator housing. As the Lead Screw Square Nut that the tube is mounted to is driven by an [8mm Lead Screw](https://www.gobilda.com/8mm-lead-screws/), the tube can extend and retract from the housing with minimal friction. To fasten something to the end of the tube, simply choose one of our 14mm clamping components.
