Unbreakable® Telescopic Umbrella Model U-303 vs. two-by-four

Model U-303 is as sturdy as the video above shows because, unlike ordinary collapsible umbrellas, its telescopic shaft, when extended, is locked by friction locks. In ordinary collapsible umbrellas, shafts are locked by small flat spring latches or ball catches. In this umbrella, no such weak parts are used for locking its shaft.

What’s more, for a shaft with friction locks to work well for many years, the shaft’s tubes cannot be made from cheap thin steel, like those of ordinary umbrellas. Therefore, tubes of the shaft of our model U-303 are machined from strong materials — high quality tool steel and aircraft aluminum — but these materials are expensive and working them is expensive too, so to make model U-303 affordable, we sell it as a kit for DIY assembly, so you may assemble it, and thus save on the cost of an assembly at a factory.

Unbreakable® Telescopic Umbrella model U-303 is sold as a DIY kit, to be assembled by buyers. This is to keep it affordable.

These are the parts and tools needed for assembly of Model U-303, which is simple with easy-to-follow video instructions. To see the assembly instructions, click here.

The Unbreakable® Telescopic (Collapsible) Umbrella protects

The Unbreakable® Telescopic (Collapsible) Umbrella protects against rain and many other things. . . . Whacks as strong as a steel pipe — it weighs 1 lb and 3.2 oz (545 g).

  • Does not bring any unwanted attention
  • The best-dual purpose accessory
  • Protects against rain and many other things….

BTW, the umbrella’s finial (the large screw at the center of the umbrella’s canopy) is made of carbon steel, and massive enough to serve as an Emergency Car Window Breaker.

Self-Defense with the Unbreakable® Telescopic Umbrella

Our Unbreakable® Umbrella’s looks do not arouse suspicion, it can be carried everywhere, and it protects from rain (it is covered in state-of-the-art waterproof fabric). Anyone who can use a baton or a club for defense can use this umbrella.

Our Unbreakable® Telescopic Umbrellas model U-303 perform in rain and wind just like the highest quality rain umbrellas. Frames of Unbreakable® Telescopic Umbrellas Model U-303 are hand-made, with telescopic shafts made of high-strength steel and aircraft aluminum, and canopy supports of polyester-fiberglass laminates. Telescopic shafts of these frames can support well over 100-kg (220-lb) weight when fully extended and, if not abused, will last more than a lifetime. Frames of Unbreakable® Telescopic Umbrellas are warranted not to break under normal use (see our Limited Five (5) Year Warranty).

Unbreakable® Telescopic Umbrella Model U-303 — How to Use It. Pay special attention to a procedure shown from minute 2 (2:00) to minute 2 and 55 seconds (2:55).


Unbreakable® Telescopic Umbrella Model U-303 — How to Assemble It.

Please note: The end tube of the Unbreakable® Telescopic Umbrella Model’s U-303 telescopic shaft is made of high-strength construction steel, not stainless steel, and so are parts inside that tube. Should water get inside the shaft, the shaft should be removed from the canopy, and the retaining-spring’s assembly should be unscrewed from the shaft, so to remove water from the shaft, dry its inside, and then oil it. Oiling is to be done by putting a drop of machine oil inside the end tube and then moving the friction-release mechanism back and forth by the umbrella’s handle.

Whenever your umbrella gets wet, leave it open to dry. Allow your umbrella’s canopy to dry fully before folding. Otherwise, mold will grow on the umbrella’s fabric. As mold grows, it creates enzymes, which digest the fabric’s fibers on which it is growing, causing permanent fabric damage and weakening, with a result like this case described.

The Unbreakable® Telescopic Umbrella is for defending against….

IMPORTANT!
Our Unbreakable® Telescopic Umbrella is for defending against elements (in every meaning of the word) and not for clowning. It is covered in a high-quality waterproof fabric, not in abrasion proof or slash proof fabric, because it has to look, weigh, and work like a normal umbrella, so do not expect this fabric to be undamaged if you strike objects with the Unbreakable® Telescopic Umbrella.

REMINDER
The Unbreakable® Telescopic Umbrella Model U-303 is compact U-303 (10.4 inch long) but weighs more than one pound (1 lb 3.2 oz or 545 g), feels massive in a hand, so if allowed to be handled by strangers, it is more likely to arouse their curiosity than our walking-stick umbrellas or U-212s. This has implications for air travel.

Why does the U-303 use an ABS handle instead of a glass-reinforced polypropylene one like that of the U-212? Is there a reason for the change? Tom asked on 2026-01-06 @ 18:58

The first reason you may see at https://youtu.be/lSAixGj1OyQ

The second reason: Time.

The third reason: Cost.

Just put together my new collapsible umbrella and was messing around with it. I extended and collapsed it several times but now it's stuck in the extended position. I don't want to break anything so I figured I'd reach out. I am experienced in the use of extendable batons/ASPs so I understand the concept, I just don't want to do anything rash with my new umbrella. Martin F. asked on 2025-12-29 @ 22:40

The stronger the swing, the stronger the friction lock, and the more strikes of the friction-lock release's striker are needed to release the lock.

How difficult is it to assemble the telescopic umbrella? JH asked on 2025-12-29 @ 16:26

Info on the assembly, with a link to a video showing the assembly process, is in the model U-303's description. Just click on the Description tag and read it. But, if you have to ask, the assembly is likely too difficult for you. Please don't buy it.

Does U-303 come fully assembled or do I have to assemble it myself? I prefer to purchase fully assembled. K asked on 2025-12-07 @ 14:20

U-303 is sold as a DIY kit, to be assembled by buyers. People who can’t assemble the U-303 correctly, can't use it correctly either, so they should not buy it.
