Cast Iron Weight Plate Marbo Slim 20kg 31mm
Description
Marbo Slim cast iron weight plate 20 kg 31 mm
We are pleased to present our new product, a 20 kg cast iron weight plate with a unique shape.
Forget half-measures and see that it is not worth spending money on poor-quality castings that do not hold their declared weight and have holes so imprecise that keeping them stable on the bar is impossible. Put an end to homemade concrete substitutes and let yourself be convinced that Marbo quality means a level of training comfort and refinement you have not known before.
We want to offer you exactly what you expect - plates that are as thin as possible. We have excellent news: our plates are only 1.4 to 3.4 cm thick. This guarantees that you can fit as many weights on the bar as you want.
We work with a large, professional Polish foundry, so you are guaranteed a top-quality product that meets all European standards.
We assure you that weights from Marbo-Sport are the best choice you can make. The central hole is perfectly matched to the bars we produce, ensuring exceptional stability during intense training. There is no question of an ill-fitting hole, play, wobbling or rattling.

The Weight line - the best bars and weight plates
At first glance it may seem that nothing groundbreaking can be done here. As we know, appearances can be deceiving.
The Marbo weight plate has undergone a true revolution - a completely transformed, unique and original look for weights in three diameters, perfectly matched to our bars. The renewed, excellent quality is reason enough to distinguish them by creating an entirely new series.
To ensure the safety of your customers, our equipment has been tested for safety and compliance with applicable standards by the European Quality Centre.
The result of these tests is the Safety Certificate and the Top Security Certificate, which we received for products from the Weight line.
