Here are some custom Timber Stop Log Panels we built recently for a customer in Quebec. These are 11-7/8″ thick x 35″ wide (tall) x 18′ long. They are Douglas Fir Structural Timber complete with hardwood splines and neoprene seals. These have lifting pins to match a lug loader beam. All Stop Logs are custom made, each job has different requirements. In this case 2 of the panels had cement “stick out shelves” that the panels had to sit against. Interesting business, for interesting clients!
