Hi Jorge,
Thank you for your question. To assist you we just now added another PDF document. Please go to this product page and look under the tab titled, "Specifications". On the right side under Construction Details there 2 documents available at this time. We may be able to find more, however because of the holiday our factory is closed. If these are not good enough, please give us a call on Monday.
Thank you,
The Koffler Team
