TIP: If pages lift from the text block, refusing to lie flat, use Polyethylene Strap to hold them down. We like using the 2" strap on the page under the page to be displayed so as to hold the bulk of the text block together with the cover. Then wrap the 3/16" or 3/8" strap around the whole book now capturing the page to be shown.
TEXT BLOCK TIP: Text Block Drag is caused by the weight of the unsupported pages pulling on the spine. This puts uneven stress on the construction of the book, distorting pages and straining the spine. To overcome this problem, we recommend the Mowery Sling: Tape a length of strap to the back of the book support plate, near the top. Place the book on the Bookmount. Move the text block out of the way, exposing the inside of the book's cover. Bring the strap down across the inside of the cover, then position the text block for display, bringing the strap up and over the text block to the back of the support plate. Secure with tape. This completes the sling.
