Welcome to our new web site! We manufacture urethane cast tunnel portals, retaining walls, abutments, culverts, bridge piers, and much more for all the popular model railroading scales. We invite you to browse our product line below.
Free Shipping
Due to the HUGE success of offering free shipping with our products, all orders over $25* will be shipped free of charge. Reduced shipping costs
for international orders.
*(excludes tree armatures; excludes dealers)
Castings
Our products are made of high-quality resin, which is very strong, almost unbreakable. They may be colored or stained with everything from dry powders to any paint (after thorough washing). Many are used right from the package because they already look like weathered wood, concrete, or rock.
Trees
We now carry tree armatures. These are mostly sagebrush twigs, with a few saltbush. Each one is different, so they are individually photographed and numbered. Since these are one-of-a-kind armatures, they are subject to prior sale. Please note that these are shipped at actual cost (you will be notified of the shipping cost before your order is actually processed).
Contact Us
Feel free to contact us at any time. For a little bit more info about our company, we have added an About Us page.
Dealers
Dealers can now conveniently order online via our password-protected Dealer Portal. To establish a new dealer account we will need your contact and shipping information, and a copy of your resale license (more dealer terms-of-sale are found on the Dealer Portal page, or contact us for more info).
