Dura Block Long block 1-3/8 H X 2-5/8 W X 24 L
Product Review (submitted on April 4, 2012):
this is my first time using a sanding block made by dura block. i love it. it is very comtrable to use unlike the cheap hard rubber sanding blocks. the adhesive backed sand paper fits and stays on while sanding and peels off very easy when your done. i would recomened a dura block sander to anyone. my door was all wavey from using a short block. and within no time of using this long block my door was straight and smooth.
