Thrust bar for bookshelf thorough comparison

Even with similar brace rods, you can choose by looking at the withstand pressure and structure

Although it is a brace bar which is often used for earthquake countermeasures, in fact there is a big difference for each product. For example, there is a difference in pressure that can be tolerated. A difference of ten times is born to the pressure which can endure at 2 ton and 200 kg. Also, most of the brace bar is screwed and used. If this screw loosens it can not support the furniture in the usual case. For that reason, some products may adopt a mechanism that is difficult to stretch, taking into consideration the case when screws are loose. In order to prepare for a big earthquake, a brace bar with appropriate performance is required. When buying a stick rod for countermeasures against earthquakes it is recommended to check the amount of suppression and structure etc. in detail and choose it.

The most recommended brace bar

■ Points

◎ Pressure resistance: Approx 2 t
◎ Even if the screw loosens, it does not stretch easily
◎ Two types left and right
Support on the surface ◎
◎ Can be reinstalled

This is a product called Tension Bar Dyna. It can be firmly fixed with two screws on the left and right, and other features are also highly efficient and can be highly recommended. Since the withstand pressure is 2t, it can be said that even large furniture is likely to be supported. Many of the brace rods were fixed by screws and the possibility of loosening it was a neck, but in the case of this brace bar Dyna it will not easily stretch even if the screw loosens. It is a point that excelled points are taken into consideration after loosening. High durability can be realized by supporting on the surface. Once installed, it is not the end, it is possible to reinstall it by stopping the screw again. Although it is safe, it can be said that it is a brace which is economically pleasing.

If it is one form, this is recommended

■ Points

◎ Pressure resistance: Approx 2 t
◎ Even if the screw loosens, it does not stretch easily
× 1 This formula
◎ Can be reinstalled

This is “Fumba-kun” which is a one-piece brace bar. 1 This formula is disadvantageous in terms of the fixing power compared with the two formulas, but depending on the installation location, there are cases where only one can not be stopped, so it is useful in such cases. This “Fu-bun kun” also has measures taken to loosen the screws, so it will not stretch easily with a slightly loose degree. Because the suppression also has 2t, it is a level that can be trusted considerably with respect to durability. Since it can be reinstalled even once it is installed, it can be used safely even when the arrangement of furniture changes. It can be said that it is a pretty excellent brace bar except that it is one form. Depending on the place to place it is not a demerit that it is one formal one, you can see that it is a brace bar excellent in usability.

Voluntary pressure, structure insecurity

■ Points

× pressure resistance: about 150 kg
× If the screw loosens it will easily stretch
△ 2 front and back
◎ Can be reinstalled

This is a product called furniture fall prevention telescopic rod M. Although it has the merit that it can be reinstalled, suppression is a level considerably painful, 150 kg. For example, if the weight of the furniture itself is around 30 kg, it will be considered sufficient to apply pressure well over 150 kg at the time of a major earthquake. If it is a small earthquake it may be okay, but it can be said that it is tough as a preparation for a big earthquake. It is also not good that the screw will loosen and stretch easily. As the brace stretches and contracts it will not be able to fulfill its role. Although it is in two formulas, it is a type that stops back and forth so it is not very strong for earthquake shaking. In general it can not be said that it is a brace stick that leaves anxiety as measures against large earthquakes.

Products only cheap

■ Points

Cheap ◎
× pressure resistance: about 140 kg
× If the screw loosens it will easily stretch
× 1 This formula
× Can not be reinstalled (drilling in pole with screw)

This stretch rod is characterized by its lower price compared with other brace rods. However, since the suppression is about 140 kg, uneasiness remains in durability. When the screw loosens it easily expands and contracts, so it can not be reinstalled because it has a structure to pierce the pole with screws. It means that you can not reinstall it because you will have to replace the furniture when you change the layout, so after all it will cost a lot of money. The fact that it is one form factor also has a negative influence on durability. There are some products that do countermeasures against earthquakes at a very low price, but since you are concerned about how useful it will be when actual earthquakes occur, be careful when choosing It is necessary.
