Pittsburgh Corning Glass Block Universal Mortar Spacer 1/4" 24/Bag

Q: Do these spacers provide sufficient space to run horizontal and vertical rebar between the block or are larger spacers required when using rebar?

The spacers give the block a 1/4" spacing each direction. With the natural cavity of the block added to the 1/4" there is plenty of room for panel anchors and panel reinforcement to be used with the spacers.

Q: It takes 2 plastic pieces to make one spacer. Does the count of 24 per bag mean 24 spacers or 24 plastic pieces?

The bag contains 24 spacers (48 plastic pieces).

Q: Will these spacers work for the 8x8x4 Decora Glass Block?

The universal spacers will work with the 8x8x4 Decora glass block. These spacers come in two pieces that snap together and depending on which holes you use, will work for either 3" or 4" glass blocks in the mortar application.

Q: Are these used for installling glass block with silicone adhesive/caulk?

No they are used for the mortar application. If you want the silicone spacers you need to find Pro-Vantage for 4" block or Residential silicone spacers for 3". We have them on our website under mortarless accessories. Call me if you need assistance 815.416.1007
