What is the difference between the two types of anchor sleeves that Portland Bolt stocks?

Portland Bolt inventories two different lines of anchor bolt sleeves, Wilson and Contec. There are many similarities between the two products, with two notable differences. The two main differences between these two types of anchor bolt sleeves are in sizing and coloring.

Wilson Sleeves
contec-anchor-sleeves
Contec Sleeves

Composition and Materials
Both brands are manufactured of high impact plastic. They are non-rusting, non-conductive and lightweight. Both are designed with a configuration that allows the grout and concrete to “lock” it in place, giving it greater pullout resistance than a regular grout pocket.

Technical Information
Both Wilson and Contec anchor bolt sleeves conform to the following technical specifications:

Plastic: High Density Polyethylene
Density, gms/cc: ASTM D 1505-68 .956
Vicat Softening Point °F: ASTM D 1525-70 256°F / 124°C
Brittleness Temperature °F: ASTM 746-70 -180°F / -118°C
Torch Application: Slow Burn
Compression Test: 180 psi / 12.7 kg/sq.cm

Differences – Sizing
Portland Bolt stocks Wilson anchor sleeves in 12 standard sizes as shown on the chart below on the left. Each size is designed to be used with one particular diameter of anchor bolt.

Portland Bolt also stocks Contec anchor bolt sleeves in the 7 “stepped” sizes shown on the chart below on the right. Instead of a standard size sleeve for each anchor bolt diameter, Contec offers a “stepped” system allowing one shell to accommodate two or more anchor bolt diameters. To size the anchor bolt sleeve, simply cut at the appropriately marked diameter line. The Contec anchor bolt sleeves are also color coded by size for ease of identification.

    These anchor bolt sleeves are apparently used little, if any, in Utah. Anyone know why? Anyone know of any independent or special testing results available to the general public? Nothing available at ICC Evaluation Service. Any transportation dept test results anywhere?

    Does your company have any plastic sleeve for a bi-metal connection (let’s say aluminum and steel), I have had a hard time trying to find a sleeve for this type of connections and I was thinking of using pvc. Is there any specs or special sleeve for this type of connections?

    @Juan Pinheiros, Portland Bolt does not have anything like this in stock, but as a specialty manufacturer, we’d be happy to look at your requirements and see if it is something we can manufacture.
