Max Field Posted August 31, 2019 Share Posted August 31, 2019 I have a wooden 2x4 wall spreader, about 11.5ft wide. If it's going into dry-wall, what exactly is the weight limit before it begins to slip? Link to comment Share on other sites More sharing options...
JD Hartman Posted August 31, 2019 Share Posted August 31, 2019 Will the load be at the center of the 11 and a half feet or more towards one end? That will be one factor in determining the amount he wood will defect at a given load. What type of wood? SPF, "white wood", something else? Kiln dried or S-Grn? Are the base plates of the spreader directly over a stud or do you intend to use scabbing to bridge the studs? Link to comment Share on other sites More sharing options...

JD Hartman Posted October 19, 2019 Share Posted October 19, 2019 His test is the spreader up against a plywood wall. A different scenario than the same spreader against a plaster or sheetrock wall. The plywood isn't going to crush or crumble as pressure is applied. Link to comment Share on other sites More sharing options...
