The t-clip is a hidden fastener that is used to install hardwood decking, such as Ipe.  This t-clip is made from extruded aluminum and is then powder coated.  Your decking product can be cut with a buscuit cutter on site, or it can be "pre-grooved" from the factory.  The t-clip can be nailed or screwed to the framing lumber for many years of service.  One bag of t-clips will cover 115 square feet of decking.
