Question 1

Is bare telescoping tubing assembled, or just loose tubes?

Accepted Answer

Upsilon’s Bare Telescoping Tubing arrives assembled. The sections are nested, your chosen lock is in place, the telescoping force is set and the retention feature is done, so it extends, retracts and locks as soon as you unpack it. Only the head and tail parts are missing: grips, end caps and functional heads.

Question 2

Can one order mix different materials and diameters?

Accepted Answer

Yes. Upsilon’s Bare Telescoping Tubing has no MOQ, so the most common trial order is a small batch each of two or three diameters for side-by-side testing. Many customers take a few dozen pieces first to check tube quality, tolerance and finish, then scale up on the second order.

Question 3

Can bare telescoping tubing carry my logo?

Accepted Answer

Yes. Upsilon prefers laser engraving for logos on Bare Telescoping Tubing: we have the machines in house, so it works even for small batches. Printed logos (silk-screen, transfer printing, hot stamping and UV printing) need a minimum quantity. A good path is to test without a logo, then confirm logo position, color and process on a pre-production sample.

Question 4

What colors are available for bare tubing with no MOQ?

Accepted Answer

Upsilon’s Bare Telescoping Tubing with no MOQ comes in natural or black for aluminum, and natural for stainless steel and brass. Other colors are matched to your Pantone code and run with production orders that meet the 3,000 pcs per SKU MOQ. Test structure and feel in natural or black first, then confirm the color on a pre-production sample.

Question 5

What if the size I need isn’t in the stock tables?

Accepted Answer

Upsilon recommends starting from its 100+ stock sizes. A telescoping tube is several nested diameters plus internal parts, so one new size often means changing a whole set, not one die. Stock sizes need no tooling and reach the market faster. Aluminum sizes outside the table need a new die in 30–45 days, which belongs to you; stainless and brass are evaluated within Ø2.8–23 mm and a 0.2–0.4 mm wall.

Question 6

I’ll fit my own grips and end caps. How do we match sizes?

Accepted Answer

Upsilon provides tube-mouth fit dimensions and tolerance recommendations with your order, so your grips and end caps fit snugly. If you would rather we make those parts too, by CNC machining or tooling, the order becomes Semi-Finished, with the fits designed together with the tube.

Question 7

Is the quality the same as in mass production?

Accepted Answer

Yes. Upsilon’s Bare Telescoping Tubing goes through the same process and inspection as mass production: ±0.05 mm wall on precision-drawn stainless and brass, ±0.1 mm cut length per section, and six inspection steps with every piece checked, no sampling. The first piece and the last are nearly identical.

Question 8

Can I get a sample first?

Accepted Answer

Yes. Upsilon makes telescoping tube samples in 7–10 days, in the same material and process as production, so you can verify tube quality, tolerance, finish and feel. Samples are charged, and the fee is credited against your production order; shipping is not included.

Question 9

What does a typical bare tubing order look like?

Accepted Answer

A typical Upsilon Bare Telescoping Tubing order: a pet brand developing a car pet barrier pole orders two-section aluminum round tubing, about 90 cm (35 in) collapsed and 130 cm (51 in) extended, and takes 300 pieces to test with its own end pads.
