Talon®Hooks were designed for 1/4" thick pegboard with 1/4" holes (some boards have 9/32" holes which are ok too), spaced 1" apart.
Talon®Hooks have performed well with pegboard dimensional variances for many years. The hook in the rear that engages the thickness is actually bent to absorb variances. The locking collet is also quite capable of dealing with variances.
They will also work quite well on the 3/16" boards sold at the big box stores. They will not fall off, however there will be a very slight space/gap between the hook and board. This will not affect performance of the hook. To shim the thickness variance, a 1/4" flat washer can be placed behind the hook to assure a firm, snug fit.
TalonHooks pegboard hooks work on most masonite and plastic boards. With so many new options in the pegboard market, however, it can be hard to tell if our hooks will be compatible with your particular board. Please email us with any questions you may have.
Soon to come! Various spacers that will allow TalonHooks to fit most boards on the market.
