Wood thresholds can be stained scratched and dented as well. Some manufacturers have now manufactured plastic covers to protect their exact thresholds dimensions and include the covers with the complete door unit. There are other pre-molded protectors available from online suppliers of temporary protection products. There are also a variety of tapes that can be used for threshold protection.
These protectors can be made from molded plastic or cardboard. Pre-molded plastic protection works well for jambs with standard door casing widths. For larger jambs there are several wrap-around jamb protectors that work similarly but are not molded to an exact casing size.

Less expensive cardboard protectors wrap around jambs in a similar fashion and cost considerably less than their plastic counterparts. These are available from a wide range of manufacturers can be purchased online or in construction supply stores as well.
