The plumb bob uses the law of gravity to indicate that the position of a construction element is really vertical. The principle on which the operation of the plumb line is based is very simple: the rope suspended with the weight that it has in its lower part must be vertical and perpendicular to any other level plane with which it crosses.
Plumb bobs continue to be, today, one of the most important tools used by the bricklayer in the construction sector.
For this reason, RUBI has a selection of models that, without renouncing traditional use, guarantee correct operation and ensure product quality.
RUBI plumb bobs are made of bichromated steel, to ensure good resistance to corrosion, due to the working conditions to which the product will be subjected.
The geometry of the weight of the RUBI sinkers maintains, in the most faithful way, one of the most traditional models: the cylindrical, with a pointed end, as an indicator of the center of gravity. With its 600 gr. weight, RUBI sinkers are highly reliable and very resistant.
The diabolos, or nuts, of the RUBI sinkers are made of wood and are varnished to give them greater resistance to work in adverse conditions.
The RUBI plumb bob rope is made of high quality cotton, to withstand the working conditions on site, 5 meters long.
This range of products, like the rest of the ranges in our catalog, is designed to offer the user time savings and increase efficiency in their work. At RUBI we know the importance of efficiency and time saving today, therefore, our product development managers are very focused on these concepts when designing new tools.
