What is T ruler and what is it for?
Known as one of the oldest tools in the world of architecture, the T ruler is one of the instruments used in order to develop technical drawings.
This ruler is used together with the square. However, sometimes it must be used alone in order to make parallel line traces.
The product has a T shape, with the smaller side composed of the head that may or may not have the same materials as the ruler itself. The models are 80 centimeters maximum, made of wood or plastic.
How to use T ruler?
In the case of fixed structures you must support the head next to the table with or without a projector. In flexible versions, you must first unscrew the head and then place it in the correct position (on the side of a table).
The head of the ruler T must be very well fixed on the table for you to enjoy the best that the tool can offer.

T-ruler : Among the most popular architectural tools is the T-ruler. With it you don’t need to tie anything to the drawing board, the structure works in different sizes or types of tables.
Production has only one foothold. For this reason it is necessary to use the ruler T in the proper way, with both hands, avoiding angulations.
Parallel ruler : In the case of a parallel ruler, both ends have support on the drawing board, which makes it easier to work parallel to the drawing, without the need to use both hands.
As a disadvantage this ruler cannot be used on common tables because of the short side ropes to tie.
Keep an eye on the differences in the rules as you follow the chart below:

Purchasing criteria: Factors to compare T-ruler models
Do not forget that to make the most of the design features, you need to know how to differentiate the best from the worst models, so that you can choose the best T-ruler. The 5 best comparator criteria for T-ruler versions are:
Follow the meaning of each item listed as you continue reading.
In day-to-day running it is common to hit the ruler in one corner or another, especially when it is in the backpack. Although these products are resistant, when strong friction occurs, production can break, putting your investment in check.
For this reason many people choose to buy offers of rulers that also have the famous protective case, which is not heavy, but serves to protect more effectively.
The productions most resistant to falls and friction are composed of wood. Preferably, buy editions that have hardwood composition, mainly: Ipê, Cumaru or Carvalho, models that have high levels of Janka hardness – a measurement unit that serves to demonstrate how hard a wood can be.
If you value durability, also choose the T-rules that have treatment to avoid warping or termite attacks. Varnished models cost higher prices, although they are more resistant and durable.
The environment in which you work determines the choice of material. For example, those who design projects outdoors, at the construction site, can choose the plastic versions. They do not stay with fungi and resist rainwater or other bad weather.
To draw indoors you must invest in wooden rulers, as there will be no contact with natural elements such as: earth, water, sun, among others.
If you think that a T-board with 100% hardwood in the entire composition is something very expensive or heavy, you can invest in the mixed structures. There are versions of wooden body and plastic head, or vice versa.
You want to buy a T-ruler with a tailstock to make it easier to move your product from your office to the classroom, correct? No problem, as long as you buy versions that have quality in the screw.
To thread or unscrew it is necessary to move a kind of screw present in the center of the head on the tool. If it is difficult to move it from side to side it will be necessary to force it, which ends up breaking the ruler T.
Therefore, before purchasing your T-head with a tilting head, it is better to find out if the store or the sellers offer a guarantee. It must guarantee exchange or refund in case of problems related to opening via screw.
Sooner or later you need to use a protractor to add something to the project.
There are T-ruler editions that offer this accessory as an addition, making the architect’s life easier, making work practical with less extra rulers on the table.
