Palmer DIY Wheelchair Ramps is a simple DIY project where anyone with even limited diy skills can build a safe, sturdy wheelchair ramp up to 16' long in 2 hours...installation and optional handrails will take longer. Longer ramps and ell shaped ramps are available but are not sold in Amazon listing. Note: WOOD is NOT included (imagine shipping cost for 12' long 300# of wood). To achieve the lowest project cost, customers purchase wood and materials locally from HD, Lowes, etc. Our DIY product offering is composed of top and bottom aluminum brackets, complete step by step instructions, tools list and materials list (for what you buy locally) and phone support throughout your project. The ramp deck is 33" wide. The top bracket is 30" wide to fit a 32" doorway threshold. The bottom bracket is 32" wide and extends the length of the ramp 9". Optional top bracket to accommodate outward swinging doors (std top will not work) can be substituted at no additional charge. Buyers will receive an Amazon email upon receipt of the order with info we need, or you may do a google search. It is very IMPORTANT to have a 10 minute telephone design consult with us to make sure the ramp size and slope will fit your unique situation and the property. If it is determined the ramp you envision is not appropriate, you can cancel the order and avoid paying return shipping costs. RETURN POLICY customers must request returns via your Amazon account Order History located in black top banner (right side). We refund 100% of the Product Cost if protective paper is still on aluminum brackets. Customers are responsible for shipping costs in either direction. Shipping is only available in continental US. No expedited shipping is available. Same day shipping for Design Consults completed in the morning, central std time
